The presence of highlights, which in dielectric inhomogeneousobjects are linear combination of specular and diffusereflection components, is inevitable. A number of methodshave been developed to separate these reflection components.To our knowledge, all methods that use a singleinput image require explicit color segmentation to deal withmulticolored surfaces. Unfortunately, for complex texturedimages, current color segmentation algorithms are stillproblematic to segment correctly. Consequently, a methodwithout explicit color segmentation becomes indispensable,and this paper presents such a method. The method is basedsolely on colors, particularly chromaticity, without requiringany geometrical parameter information. One of the basicideas is to compare the intensity logarithmic differentiationof specular-free images and input images iteratively.The specular-free image is a pseudo-code of diffuse componentsthat can be generated by shifting a pixel's intensityand chromaticity nonlinearly while retaining its hue. Allprocesses in the method are done locally, involving a maximumof only two pixels. The experimental results on naturalimages show that the proposed method is accurate and robustunder known scene illumination chromaticity. Unlikethe existing methods that use a single image, our methodis effective for textured objects with complex multicoloredscenes.
