A PHYSICS-BASED APPROACH TO IDENTIFYING INTERREFLECTION

A reflection model which enables an identification of matte, highlight and interreflection legions on objects of inhomogeneous dielectric ma terials is presented. The model utilises the concept of the dichromati c reflection model and the one-bounce model of mutual reflection. A ps i-theta space is introduced to enable the spectral cluster of a region to be identified either as a matte hill, a highlight lobe or an inter reflection lobe. An analysis of the boundary of clusters enables the u se of the K-means clustering algorithm to segment the regions without the need to specify the expected number of clusters and the initial cl uster centres.
