Systems, apparatus, articles, and methods are described below including operations for real-time face beautification features for video images.

As described above, video sharing and conferencing has been increasingly used with the pervasive usage of smart phone. However, many of the existing apps for smart phones are designed for off-line image processing or might not work with out limited features in a video mode.

However, as will be described in greater detail below, some of the implementations described herein may present a new set of face beautification features including cute nose, happy/sad face, eye wrinkles removal, eye bags removal, and/or dark eye circles removal. The fundamental techniques enabling face beautification features utilized herein are morphological operation and image enhancement where both are applied based on analytic information on the face area. The information utilized from face analysis includes face shape, facial landmark positions and skin tone likelihood/score.

Some of the implementations described herein may utilize a complete face beautification (FB) pipe. The analytic information utilized in such a FB pipe may include face shape, facial landmark points and a skin tone score. The pipe may combine information of face shape, facial landmark points and skin tone score and may utilizes a GPU sampler engine fully.

The face beautification (FB) pipe may be an intelligent FB solution where customized processing is embedded. That is, the features with corresponding levels of processing to be applied to users differentiated by gender/age/racial under different environments are selected automatically and visually suitable/pleasant augmented results are obtained.

FIG. 1 illustrates diagram of a face beautification (FB) video augmentation pipe 100 (the features set are not limited by this diagram). The whole pipe 100 is deployed on a graphics processor (e.g., with GPGPU kernels and GPU fixed function). As illustrated, the beautification features in video augmentation pipe 100 may be based on analytic information of skin-tone likelihood/score or facial landmark points. The whole process can be split to five areas: video pre-processing, application of skin tone based filters, application of facial landmark based filters, face recognition/profile detection filter, and display of the processed video and/or encoding for transmission.

In video pre-processing, the input video 101 (captured by camera or video clip) is firstly sent to the GPU video augmentation pipe 100 for skin tone detection (see VEBox-STD 102 and box filter 104) as well as facial shape/feature extraction (face detection 106 and landmark detection 108). The skin tone detection may be done on GPU fixed function (video enhancement box 102). At the same time, the facial shape/feature extraction kernels 106/108 (GPGPU kernel) may be dispatched to execution unit on GPU.

In the application of skin tone based filters, skin tone based filters may include face brightening 110, face whitening 112, skin tone enhancement 114, skin foundation 116, skin smoothing 118, the like, and/or combinations thereof (Note: the feature set may be expanded and/or the order of this feature set might be changed). The processed skin tone map from skin tone detection and box filter modules 102/104 will be consumed by these filters. Algorithm flow charts of skin foundation filter 116 and skin smoothing filter 118 are illustrated below.

In the application of facial landmark based filters, the landmark based filters include red lip filter 120, big eyes filter 122, slim face filter 124, cute nose filter 126, happy/sad face filter 128, eye wrinkle remover filter 130, eye bags remover filter 132, dark eye circles remover filter 134, the like, and/or combinations thereof. Algorithm flow charts of the algorithm flow charts of red lip filter 120, big eyes filter 122, slim face filter 124 are illustrated below.

The face recognition/profile detection filter 140 may be optional. If face recognition/profile detection filter 140 is turned on, face recognition/profile detection will be used to customize the feature set. For example, when gender detection is on, red lip filter 120 may be turned off for male. Further, when face recognition/profile detection filter 140 is on, a user may be able to customize the setting (filter on/off, filter strength, etc.) and save the configuration for future use. That is, the features with corresponding levels of processing to be applied to users may be differentiated by gender/age/racial under different environments are selected automatically and visually suitable/pleasant augmented results are obtained.

The processed picture 141 may be shown on a display and/or encoded and transmitted.

In operation, the video augmentation pipe 100 may leverage existing fixed-function STDE hardware (e.g., Skin Tone Detection and Enhancement 102 module) on a GPU, which may be low-power and high-performance to generate the skin-tone likelihood. For further information of such STDE hardware (e.g., Skin Tone Detection and Enhancement module), e.g., please refer to U.S. Pat. No. 8,493,402, filed Jan. 6, 2011, and titled “System, method and computer program product for color processing of point-of-interest color”.

The generation of facial landmark points, on the other hand, may leverages both a face detector, e.g., please refer to PCT Application No. PCT/CN2014/075165, filed Apr. 11, 2014, entitled “OBJECT DETECTION USING DIRECTIONAL FILTERING”, and fixed-function hardware (e.g., Convolution Filter), e.g., please refer to PCT Application No. PCT/CN2012/086840, filed Dec. 18, 2012, entitled “HARDWARE CONVOLUTION PRE-FILTER TO ACCELERATE OBJECT DETECTION”, for the face detection 106 task, which may be performed prior to facial landmark 108 detection. The face detection 106 approach taken here can achieve fast-compute and low-power target while maintaining excellent detection accuracy.

Furthermore, a light-weight compute of facial landmark validation step may be embedded in the facial landmark 108 generation block to intelligently switch between detection and tracking mode. This automatic switch between tracking and detection mode may help reduce the compute while maintaining good accuracy in terms of locating facial landmark.

Some of the implementations described herein may combine GPU based face detection, skin tone detection, facial landmark detection and fully utilizes GPU hardware (e.g., Sampler engine, EU, Fixed Function, etc.) to build one power efficient real-time face beautification pipe on HD-resolution video.

For example, in experiments run at HD (1280×720) on an Intel GPU @400 MHz, a face beautification video augmentation pipe 100, as described herein, achieve real-time (e.g., 30 fps) on HD video with very low CPU utilization and can use multiple face beautification filters simultaneously.

Additional details regarding the functioning of face beautification (FB) video augmentation pipe 100 are illustrated below with regard to FIG. 2.

FIG. 2 illustrates an example flow diagram 200 of face based video augmentation on a graphics processor. The blocks 202 and 204 represent the analytic components (e.g., a skin tone logic unit 202 to generate skin-tone likelihood/score 202 and a facial feature logic unit 204 to generate facial landmark points) of the system; the blocks 206 represent the features utilizing skin-tone likelihood information while the blocks 208 represent the features utilizing the facial landmark information.

The Skin-Tone Detection (STD) 102 utilizes Video Enhancement Box (VEBox) Skin-Tone Detection and Enhancement (STDE) in a graphics processor to perform skin tone color detection for an input YUV data. The output of the STD contains is skin-tone likelihood score represented in 5-bit for each pixel within an input frame.

The input of the Box-Filter 104 is the skin-tone score result from Skin-Tone Detection (STD) 102 (e.g., VEBox). Box-Filter 104 performs averaging operation on the input skin-tone score to produce a smooth version of skin-tone likelihood score.

The Face Detection 106 takes YUV input and applies a pre-trained model, which only operates on Y-channel information to identify the appearance of human faces within an input frame. Face Detection 106 returns the location and size of each detected face. In some implementations, face detection 106 may be implemented as a combination of hardware and software solutions.

The Facial Landmark Detection/Tracking 108 takes YUV input and information of detected faces from the Face Detection 106. Facial Landmark Detection/Tracking 108 applies a pre-trained model on the rectangle area of each detected face to detect/track the locations of a set of pre-defined facial landmark points (e.g., point of corners of eyes, points of the corners of the lip . . . etc.). The output of the Facial Landmark Detection/Tracking 108 contains the locations of the set (e.g., N points) of facial landmark points.

The Face Brightening 110 takes YUV input data and performs adjustment on Y data based on the skin-tone likelihood/score information fed from the analytic module Skin-Tone Detection (STD) 102 to produce brightening effect of the input frame.

The Face Whitening 112 module takes YUV input data and blends the input with a white color map. The white color map is input content-adaptive and is generated within the Face Whitening 112 module. The blending of the input pixels and the white color map is per-pixel wise, adaptive to the Y value of each pixel.

The Skin-Tone-Enhancement (STE) 114 utilizes Skin-Tone Detection (STD) 102 (e.g., VEBox) to perform the saturation enhancement on the skin-tone-color pixels where the enhancement is adaptive to the skin-tone likelihood score.

The Skin Foundation 116 module takes YUV input data and blends the input with a user-selected foundation color where the per-pixel skin-tone likelihood score serves as the blending factor here.

The Skin Smoothing 118 takes YUV input data and adjust all 3-channel information to produce a smooth version of the input.

The Red Lip 120 module takes YUV input data. With the facial landmark information fed into the Red Lip 120 module, the module identifies the lip area of the face if there is a face within the input frame. For input frame with detected faces, Red Lip 120 module further performs color modification for lip area so that a visually pleasant appearance of the users' lips can be obtained.

The Big Eyes 122 module takes YUV input data. With the facial landmark information fed into the Big Eyes 122 module and the users' preference of level of enlargement input from the Application, the Big Eyes 122 module internally derives the proper location within the face and the shape of the eyes users intend to have. Morphological warping is performed following to create the big eyes effect.

The Slim Face 124 module takes YUV input data. With the facial landmark information fed into the Slim Face 124 module and the users' preference of level of slim-face-effect input from the Application, the Slim Face 124 module internally derives the thinner-shape of the original face area and performs morphological warping to create the slim face effect.

The Cute Nose 126 module takes YUV input data. With the facial landmark information fed into the Cute Nose 126 module and the users' preference of level of adjustment input from the Application, the Cute Nose 126 module internally derives the modified shape of the nose area and performs morphological warping to create the narrower/cuter nose effect.

The Happy/Sad 128 module takes YUV input data. With the facial landmark information fed into the Happy/Sad 128 module and the users' preference of level of adjustment input from the Application, the Happy/Sad 128 module internally derives the modified shape of the mouth area and performs morphological warping to create the happy/sad face effect via changing the shape of users' mouths.

The Eye Wrinkles Removal 130 module takes YUV input data. Facial landmark information, rectangle region of the detected face, and Y-channel signal analysis are utilized by the Eye Wrinkles Removal 130 module to locate the area around eyes for processing. Once identifying the target area, a smoothing process is operated on YUV values for pixels within the area to create the wrinkles removal effect.

The Eye Bags Removal 132 module takes YUV input data. Facial landmark information and Y-channel signal analysis are utilized by the Eye Bags Removal 132 module to locate the eye bags regions for processing. Once identifying the regions, a smoothing process is operated on YUV values for pixels within the regions to create the eye bags removal effect.

The Dark Eye Circles Removal 134 block takes YUV input data. Facial landmark information and Y-channel signal analysis are utilized by the Dark Eye Circles Removal 134 to locate the eye bags region for processing. Once identifying the regions, a content-adaptive blending is performed to blend the original YUV values and a pre-defined color value for pixels within the eye bags region. The effect of removing dark eye circles is finally resulted.

The skin-tone enhancement feature 206 shown in FIG. 2 may leverage the existing fixed-function hardware (e.g., Skin Tone Detection and Enhancement 102 module) on a GPU, which is low-power and high-performance solution for color enhancement. Further, the facial landmark feature 208, specitically for all modules where warping operation is involved (e.g., Big Eyes, Slim Face, Cute Nose, Happy/Sad Face), may leverage a fixed-function sampler engine (see FIG. 3) on a GPU may be utilized to do the warping operation. With such an implementation of the skin-tone enhancement feature 206 and the facial landmark feature 208, the pipe 100 (see FIG. 1) with rich feature set for video mode can achieve high-performance and low-power target.

FIG. 3 illustrates an example face beautification (FB) video augmentation scheme 300 implemented on a mobile platform GPU 302. In the illustrated example, mobile platform Graphic Processing Unit (GPU) 302 may have several available hardware blocks (e.g., independent types of engines) with distinct functionalities. For example, GPU 302 may include video codec engine(s) 304, video processing engine(s) 306, render/3D engine 308, sampler engine 310, an array of cores 312, the like, and/or combinations thereof.

Video codec engine(s) 304 may perform video encoding/decoding. For example, video codec engine(s) 304 may include Decode Engines for video decoding and/or Encode Engines for video encoding.

Video processing engine(s) 306 may perform video pre-post-processing. For example, some parts of video augmentation pipe 100 (e.g. see skin tone detection VEBox-STD 102 and skin tone enhancement VEBox-STE 114 of FIG. 1) may be implemented via video processing engine(s) 306. Most of the rest of video augmentation pipe 100 may be implemented via array of cores 312, as illustrated.

Render/3D engine 308 in combination with array of cores 312 may perform rendering, gaming, the like, and/or combinations thereof.

Sampler engine 310 is a separate module (e.g., separate from video processing engine 306) inside GPU 302. For example, sampler engine 310 may be implemented as a hardware module to allow quick sampling access to get the pixels/texels from the original data map, and to allow quick filtering operations.

FIG. 4 illustrates an example of a flexible virtual GPU 400 configuration implemented on a sever platform GPU 402. In the illustrated example flexible virtual GPU 400 may include several virtual GPUs 412 (e.g., VM_0, VM_1, and VM_2) that share one physical server GPU 402. In such an example, a first virtual GPU 414 (e.g., VM_0) may run a transcoding application, a second virtual GPU 416 (e.g., VM_1) may run a gaming application, while a third virtual GPU 416 (e.g., VM_2) may run a facial beautification application. Accordingly, sever platform GPU 402 may transfer input video images as well as output video images modified by the facial beatification operations described herein between one or more remote devices in communication with sever platform GPU 402.

Often, the type of chips used in servers and mobile devices differ. Accordingly, it may be advantageous to develop server chips that reproduce the functionality of chips for mobile devices. To serve users possessing mobile platforms not equipped with a facial beautification chip, a customized virtual graphics devices may be provide via a cloud-based facial beautification solution. This cloud-based facial beautification solution may have the advantage over power efficiency compared to other cloud-based FB solution which is purely CPU software solution.

In the illustrated example, server Graphic Processing Unit (GPU) 402 may have several available hardware blocks (e.g., independent types of engines) with distinct functionalities. For example, server GPU 402 may include the same and/or similar hardware blocks as mobile platform Graphic Processing Unit (GPU) 302 of FIG. 3. For example, server GPU 402 may include video codec engine(s) (not shown here), video processing engine(s) 406, render/3D engine(s) 408, sampler engine (not shown here), an array of cores (not shown here), the like, and/or combinations thereof. For any type of engines listed above, there may be multiple instances included in the GPU 402.

With the emerging of Virtual Desktop Infrastructure (VDI) and general-purpose computing on graphics processing units (GPGPU), GPU virtualization technology may be implemented in cloud computing. In such kind of usage scenarios, one powerful physical GPU 402 on the cloud side may be shared by multiple Virtual Machines (VMs) 412. Note that from a VM's 412 point of view, VMs 412 exclusively owns the virtual graphics device.

Further, as one can see from FIG. 4, the proposed flexible virtual GPU 400 configuration is not limited to face beautification workload in terms of its application. Instead, flexible virtual GPU 400 configuration can be easily applied to cover other workloads such as GPGPU, transcoding, the like, and/or combinations thereof.

The proposed cloud-based facial beautification solution has advantages of both performance and power efficiency compared to others due to two distinct system-wise factors. First, the flexible virtual GPU 400 configuration allows for utilization of GPU instead of CPU; thus better performance may be achieved. Second, the flexible virtual GPU 400 configuration allows for utilization of virtual graphics devices to allow for sharing of the GPU with other workloads; thus a minimum of power leak may be achieved.

FIG. 14 is an illustrative diagram of an example cute nose filter flow chart 1400. In the illustrated example, cute nose filter 1400 may allow users to adjust the size and shape of the look for the nose. The cute nose filter 1400 may utilize the facial landmarks around the nose area to calculate the warping map. A GPU sampler engine (See FIG. 3) may then be used to operate the warping process to obtain the nose with adjusted size and shape.

As illustrated, step 1402, may operate to derive the affected transform radius R, transform center C, translation vector CM for the nose area in an input image P. For example, affected radius R, transform center C, dislocation vector CM for the nose area may be calculated based at least in part on Facial Landmark Points (of nose area) data as well as a Cute or Bigger Nose Strength setting.

While the Facial Landmark Points (of nose area) is the analytic information consumed by the cute nose filter 1400 at operation 1402, the Cute or Bigger Nose Strength setting is the feature control setting enabled either by an associated Application or by Profile Detection 140 functionality available in the Face Beautification Pipe 100 (see FIG. 1).

In some examples, the cute nose filter 1400 at operation 1402 may implement an automatic scheme to determine the morphology of the nose for cute or bigger visual appearance.

At operation 1404, backward warping by translation model may be performed. For example, backward warping by translation model may be performed for each pixel d inside the affected area to get source coordinates s.

At operation 1406, bilinear interpolation may be performed based on the output of operation 1404 and a processed image P′ may be output.

FIG. 15 is an illustrative diagram of an example happy/sad face filter flow chart 1500. In the illustrated example, happy/sad face filter 1500 may allow users to create happy or sad appearance by changing the shape of their mouth. The fundamental technique here is similar to the one enabling the Cute or Bigger Nose feature, except that now the manipulation is done based on the information of facial landmarks of the mouth.

For example, affected radius R, transform center C, dislocation vector CM for the mouth area may be calculated based at least in part on Facial Landmark Points (of mouth area) data as well as a Happy or Sad Face Strength setting.

While the Facial Landmark Points (of mouth area) is the analytic information consumed by the happy/sad face filter 1500 at step 1502, the Happy or Sad Face Strength setting is the feature control setting enabled by an associated Application. The happy/sad face filter 1500 at step 1502 may implement an automatic scheme to determine the morphology of the mouth for happy or sad appearance.

At operation 1504, backward warping by translation model may be performed. For example, backward warping by translation model may be performed for each pixel d inside the affected area to get source coordinates s.

In the illustrated example, eye bag/wrinkle removal filter 1600 may allow users to create younger appearance via smoothing the facial/skin area around users' eyes. To correctly locate the area to be smoothed out (e.g., to generate the eye bags map and the eye wrinkles map), facial landmark points of the nose and those around the eye region are utilized.

As illustrated, step 1602, may operate to generate an eye wrinkles/bags map S. For example, eye wrinkles/bags map S may be generated from luma component of the input image P based at least in part on Facial Landmark Points (of eye and/or nose area) data.

At operation 1604, a smooth version B of input image P may be generated. For example, smooth version B of input image P may be generated via recursive bilateral filtering based at least in part on a Smooth Strength setting.

For example, content adaptive blending of input image P and smooth version B may be performed based at least in part on the generated eye wrinkles/bags map S and a processed image P′ may be output.

In operation, while the Facial Landmark Points (of eye area) is the analytic information consumed by eye bag/wrinkle removal filter 1600 at operation 1602, the Smooth Strength setting is the feature control setting enabled either by an associated Application or by Profile Detection 140 functionality available in the Face Beautification Pipe 100 (see FIG. 1). The eye bag/wrinkle removal filter 1600 at operation 1602 may implement an automatic scheme to create a map where the per-pixel value inside representing the likelihood of belonging to the eye wrinkles/bags region. The eye bag/wrinkle removal filter 1600 at operation 1606 of Per-pixel, Content-Adaptive Blending may implements a blending approach taking the likelihood map information into account.

FIG. 17 is an illustrative diagram of an example dark eye circle removal filter flow chart 1700. In the illustrated example, dark eye circle removal filter 1700 may allow users to create younger appearance via whitening up the eye circle region. Facial landmark points around eye region may be utilized here to accurately locate the eye circles area (e.g., to generate the eye circles map) for processing. The dark eye circles may be eliminated by blending the pixels within the eye circles map with a slight white color value where the level of blending depends on per-pixel's value.

As illustrated, step 1702, may operate to generate an eye circle map S. For example, eye circle map S may be generated from luma component of the input image P based at least in part on Facial Landmark Points (of eye and/or nose area) data.

At operation 1704, a colored pixels F of input image P may be generated. For example, colored pixels F of input image P may be generated based at least in part on a Desired White Color setting and a Strength setting.

At operation 1706, a content adaptive blending of input image P and colored pixels F may be performed. For example, content adaptive blending of input image P and colored pixels F may be performed based at least in part on the generated eye circle map S and a processed image P′ may be output.

In operation, while the Facial Landmark Points (of eye area) is the analytic information consumed by the dark eye circle removal filter 1700 at step 1702, the Desired White Color & Strength settings are the feature control settings enabled either by an associated Application or by Profile Detection 140 functionality available in the Face Beautification Pipe 100 (see FIG. 1). The dark eye circle removal filter 1700 at step 1702 may implement an automatic scheme to create a map where the per-pixel value inside representing the likelihood of being the dark eye circles region. The dark eye circle removal filter 1700 at step 1706 of Per-pixel, Content-Adaptive Blending may implement a blending approach taking the likelihood map information into account.
