RESEARCH ON SIFT IMAGE RECOGNITION ALGORITHM COMBINED WITH RANSAC
Main Article Content
Abstract
SIFT feature extraction algorithm has good invariance in illumination, scale transformation and affine transformation. Background information is far more than the target information in the image. In order to improve the matching efficiency of the SIFT algorithm, a scheme is proposed in this paper. By using the RANSAC algorithm to optimize the spatial extreme point detection method, the wrong matching point is eliminated and the matching efficiency of the algorithm is improved.
