Illumination Invariant Color Model for Image Matching and Object Recognition

Abstract

In this paper we present a new illumination invariant color model for image matching and object recognition. The color model is defined as the ratios of the color differences between neighboring pixels for each color component. Based on the dichromatic reflection color model, it is shown that the proposed color model is invariant to lighting geometry, illumination color, specularity, and diffuse lighting. Experimental results show robust image matching and recognition of using the new color model on objects that are illuminated under different illumination colors and lighting geometry.
