Class GPUImageKuwaharaFilter

java.lang.Object

jp.co.cyberagent.android.gpuimage.GPUImageFilter

jp.co.cyberagent.android.gpuimage.GPUImageKuwaharaFilter

public class GPUImageKuwaharaFilter
extends GPUImageFilter

Kuwahara image abstraction, drawn from the work of Kyprianidis, et. al. in their publication "Anisotropic Kuwahara Filtering on the GPU" within the GPU Pro collection. This produces an oil-painting-like image, but it is extremely computationally expensive, so it can take seconds to render a frame on an iPad 2. This might be best used for still images.
