Simple and efficient method for specularity removal in an image

Abstract: For dielectric inhomogeneous objects, the perceived reflections are the linear combinations of diffuse and specular reflection components. Specular reflection plays an important role in the fields of image analysis, pattern recognition, and scene synthesis. Several methods for the separation of the diffuse and the specular reflection components have been presented based on image segmentation or local interaction of neighboring pixels. We propose a simple and effective method for specularity removal in a single… Show more

“…To cope with this difficulty, more recent methods attempt to utilize spatial information in the image [9,15,[10][11][12][13]. Instead of determining body colors first, most of these methods search for all the parameter values simultaneously through optimization.…”

“…Shen et al [11] proposed another specular-free image that is obtained by subtracting the minimum of the RGB values from them for each pixel. They proposed a simple separation method based on it and also on an incorporated prior that the body color changes smoothly around highlights.…”
