Abstract
Image feature extraction involves in computer vision techniques and image processing,and the analysis and processing of computer to extract invariant features of the image can greatly improve the image processing accu-racy and speed. This paper mainly studies three kinds of classic algorithms of image feature extraction,namely SIFT algorithm,SURF algorithm and ASIFT algorithm. By using Matlab platform,VC platform and OpenCV library func-tion,the paper simulates and debugs the above algorithms,compares the effect of three feature extraction algo-rithms,and analyzes their performances as well as advantages and disadvantages.关键词
