We present a fast 8-bit median filter implementation based on a separability argument. Our strategy is to start with a naive separable implementation of the median filter which displays O(1) time complexity per pixel, and then optimize this implementation to reduce the time constant. The optimizations that we employ include (a) lowering the histogram memory(More)
The processing power and flexibility of recent rasterization hardware permits to speed up image generation through raytracing. This paper introduces a method that performs ray processing on the GPU in parallel to shading operations on the CPU. It effectively exploits CPU-GPU parallelism in a way that can be integrated into existing implementations utilizing(More)
