| 1 | Specular Detection and Removal for a Grayscale Image Based on the Markov Random Field显示文摘Specular detection and removal has been a hot topic in the field of computer vision. Most of the existing methods are mainly for color images, but grayscale images are widely used. For a single grayscale image with only intensity information, highlight detection and removal becomes a difficult issue. To solve this problem, the single grayscale image highlight detection and removal method based on Markov random field is presented. Each reflection component modeling is estimated by geometric relation of surface normal in diffuse and specular reflection component in the framework of Markov random field. Their maximum a posteriori estimation is calculated under Bayesian formula and highlight area is detected. Finally, image inpainting method based on the BSCB model removes highlights. Experiment reveals that this method can effectively detect grayscale image specular reflection area, improve highlight areas the repair rate. | Fang Yin Tiantian Chen Rui Wu Ziru Fu Xiaoyang Yu | 2016 | 国际计算机前沿大会会议论文集2016，，1： | 0 |
