A robust image mosaics algorithm

ZHANG Hua1,2,SUN Ji-zhou1,YOU De-xiang2(1.School of Computer Science and Technology,Tianjin University,Tianjin 300072,China;2.School of Computer Science and Technology,Tianjin University of Technology,Tianjin 300191,China)  
The key problem of image mosaics is the image registration.A robust registration method is investigated in this paper.It uses Harris-based corner detection algorithm to obtain feature points,then an improvement for image entropy is made using a Euclid weighted function so as to get accurate point matches.The least median square method is employed to obtain 8 parameters of transform matrix for image stitching.The experiment shows that the proposed algorithm can get good effects in high precision matching.
