THE DICHROMATIC REFLECTION MODEL: FUTURE RESEARCH DIRECTIONS AND APPLICATIONS

Abstract: The dichromatic reflection model (DRM) predicts that color distributions form a parallelogram in color space, whose shape is defined by the body reflectance and the illuminant color. In this paper we resume the assump-tions which led to the DRM and shortly recall two of its main applications domains: color image segmentation and photometric invariant feature computation. After having introduced the model we discuss several limi-tations of the theory, especially those which are raised once working on real-world uncalibrated images. In addition, we summerize recent extensions of the model which allow to handle more complicated light interac-tions. Finally, we suggest some future research directions which would further extend its applicability.
