# BeautifyFaceDemo

基于GPUImage的人脸磨皮、美白、提亮的美颜滤镜

GPUImageBeautifyFilter是一个自定义的美颜滤镜，可以用来处理实时视频流或者是静态图片

主要原理是双边滤波、Canny边缘检测和肤色检测

# 算法流程图



# 示例代码

添加以下几行代码即可快捷实现视频实时滤镜:

 

GPUImageVideoCamera *videoCamera = [[GPUImageVideoCamera alloc] initWithSessionPreset:AVCaptureSessionPreset640x480 cameraPosition:AVCaptureDevicePositionBack];

videoCamera.outputImageOrientation = UIInterfaceOrientationPortrait;


GPUImageView *filterView = [[GPUImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, viewWidth, viewHeight)];

GPUImageBeautifyFilter *beautifyFilter = [[GPUImageBeautifyFilter alloc] init];

[videoCamera addTarget:beautifyFilter];

[beautifyFilter addTarget:filterView];

[videoCamera startCameraCapture];
