An algorithm for estimating the homography of color images
彩色图像的单应矩阵估计算法

The estimation of intra-frames homography is a key issue to image registration and mosaicing,and the conventional estimation methods are only feasible for the gray images.In this paper,the homographic matrix of two colored consecutive frames is proposed based on a hierarchical motion estimation approach.In our algorithm,the new constraints,viz.,the conservation of hue and saturation,are adopted to obtain optical flow equations and the defects of the lightness conservation are remarkably decreased.Meanwhile,...
