Abstract

This paper introduces a colour-to-greyscale conversion method using colour clustering and multidimensional scaling that preserves region integrity i.e. it preserves edge structure without low-frequency distortion. Edges can be extracted from the resulting greyscale images and the results will be close to those obtainable from the original colour image. We compare with prior-art colour-to-greyscale conversion and a recent colour-edge extractor and show superior performance in each case.
