Computational models for fusion of texture and color: a comparative study

Abstract

Fusion of texture and color is to simulate color texture images that are perceptually very close to the actual ones. There are three computational models, i.e., gray-to-color mapping (GCM), color-to-color mapping (CCM), and dichromatic-based (DICH) mod- els. The CCM model is extended to three methods, namely, CCM- RGB, CCM-LCH, and CCM-l, when it is applied in different color spaces. The DICH model contains two methods: DICH-GC and DICH-CC, considering the original image can be either gray scale or color. The color fidelity of these six methods is comparatively inves- tigated in terms of image similarity between simulated and target
