BeautifyFaceDemo
It's a simple demo of realtime face beautification based on GPUImage
GPUImageBeautifyFilter is my custom beauty filter which can be used to beautify live video or static images.
Flow Chart
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];
