Abstract
Although SIFT algorithm has great advantage of extracting the invariant features, it is a challenge to use the algorithm real-time because of the time complexity.The paper improves the SIFT algorithm by limiting the area of extremes detection.The radius of the area is updating with the global motion vectors between the continuous frames of a video.With the improved algorithm, the images of the areas are obtained in which the extremes to be detected.The algorithm keeps the amount of SIFT features and is proved to be more efficient by decreasing the time cost by extremes detection.关键词
