Application of Improved Inverse Compositional Algorithm in Image Registration
Sang Qing-bingb · Jisuanji gongcheng · 2011
Inverse compositional algorithm has a high accuracy in image registration,but it is sensitive to the initial position of the template image in input image.This paper proposes an improved algorithm based on inverse compositional algorithm.It gets the rough localization by computing Bhattacharyya coefficient between template image and input image,and applies inverse compositional algorithm to accurate image registration.Experimental results show that the improved algorithm is robust to images with affine transform and has stronger ability of image registration.
