Abstract:Due to the reality of different focus, temperature localization, etc, there produce all sorts of local fuzzy pictures. For dealing with this kind of problem, Grayscale image fusion technology has been quite mature, but in color images area it has all kinds of shortage. In order to deal with the problem that the traditional wavelet transform fusion method used in color image fusion will produce the color difference, this paper put forward based on the wavelet analysis and R, G, B three color channel binding type fusion method strategy.
