Abstract
According to the problem of long search time in detecting and matching features of image matching, so in this paper, an image matching algorithm based on KD-Tree and SURF features is researched. Firstly extract SURF features of images and create feature vectors, then build KD-Trees for these feature vectors, finally complete the image matching work by calculating the nearest neighbor vector which is nearest to each feature vector. The experimental results express that, the speed of detecting features by SURF algorithm is 2-3 times faster than by SIFT algorithm; in comparison with global nearest search, approximate nearest neighbor searching based on KD-Tree has Less calculation, so in this way, the proposed algorithm improves matching speed.关键词
