BeautifyFaceDemo

A Simple Demo of Face Beautification Based On GPUImage

It's based on Bilateral Filter, Canny Edge Detection and Skin Color Detection

Sample Code

You can easily beautify a live video using the following code:

 
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];
