Color and luminance compensation for mobile panorama construction
Yingen Xiong, Kari Pulli · 2010
This paper addresses the problem of color and luminance compensation for sequences of overlapping images where the source images have very different colors and luminance. We apply the method for panoramic image construction on mobile phones. A simple approach is proposed that minimizes both the color differences of neighboring images and the overall color correction over the whole sequence. We compare several combinations of gamma correction and linear adjustment over different color representations, and select the method with best results: use YCbCr and apply gamma correction for the luminance component and linear correction for the chrominance components
