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)

From left to right: the Stanford bunny and BART robots (with shadows), and the BART kitchen (with specular reflection). Over the past few years, advances in both software techniques and hardware performance have spurred increased research into ray tracing images in(More)
