Image mosaic in the satellite remote image,medical image processing has a wide range of application.This paper presents a modified algorithm based on SIFT feature of image,constructs a way to select points from the matched points to build affine transformation,and then builds a mosaic border based on the selected point.For the distortion of edge image by affine transformation,this paper presents an incomplete affine transformation to resolve this problem.Experimental results indicate that the method can overcome the problem of traditional affine by selecting points randomly to generate the corresponding formula,and has better stability and accuracy.
