Abstract

In order to improve the performance of scene matching guidance a novel Canny-SIFT algorithm is proposed based on Scale Invariant Feature Transform (SIFT) algorithm. The edge feature of the image is obtained by Canny operator, and the edge feature image is matched by SIFT algorithm. The Canny operator is used to extract the edge feature of image at first. Then, the edge feature image is utilized to realize matching. The simulation results indicate that the Canny-SIFT algorithm is insensitive to the change of brightness, rotation and scale, which effectively overcomes the long matching time of SIFT algorithm. More matching feature points can be extracted when the matching speed is greatly improved, and thus the matching accuracy is improved and the performance of the whole scene matching guidance system is improved.

Key words： Canny edge detection; SIFT algorithm; scene matching guidance; Canny-SIFT algorithm
