Paper Abstract

In this paper, we study image description based on compound mutual information (CMI) and its application to multimodal image registration. CMI is an aggregate information measure derived from the multiple marginal densities of image distributions. It extends histogram-based mutual information to that based on various marginal densities, which encode spatial intensity distribution and other image characteristics. Therefore, CMI can overcome the difficulties (such as the lack of spatial information) inherent in the color histogram, enrich the vocabulary of image description, and help improve registration accuracy and robustness. CMI is not sensitive to illumination and absolute appearance, and it is particularly suited for multimodal applications.
