Color image mosaic technology based on corner detection and affine transform model
Ping Wang · Jisuanji gongcheng yu sheji · 2009
An image registration method based on the corner detection and affine transform model is proposed.This method uses the Harris operator to detect the corners in the HSV space of the color images.A two-level restricted tactic based on cross match and simplified RANSAC algorithm to gain the homonymy corner points is introduced.A segment-weighted function based nonlinear characteristic of human vision is given to eliminate the mosaic line caused by the difference of the image color.The experiment indicates that this algorithm has good mosaic precision and nice fusion of pixel color.
