Abstract

In this paper, we introduce a novel colour substitution algorithm based on the dichromatic reflection model. We separate the object colour and scene illumination information in the target area of the original image. The object colour was subsequently substituted while keeping the illumination information unchanged. A new method was employed to estimate the object colour. We also developed a set of new parameters to adjust the intensity distribution on the resultant image. Our algorithm is totally automatic and can achieve more realistic effects compared with other colour substitution methods.
