摘要
Abstract
SIFT is a kind of local image feature extraction algorithm based on multi scale space,which can well applied in image matching.This paper introduced the formation of scale space,detection of the local extreme point,precise positioning of feature points location,calculation of the main direction of the feature point,generate SIFT description and image matching method based on SIFT.Experiments show that SIFT is robust to various changes in the image.关键词
