In this contribution we present experiments on color image enhancement for several different non-linear filters which originally were defined for gray-level images. We disturb sample images by different types of noise and measure performance of the filters. We provide signal-to-noise measurements as well as perceived color difference in ΔE as defined by the CIE. All images and test programs are provided online on the internet so that experiments can be validated by arbitrary users on any image data.
