Web以经典的SIFT特征点检测算法为参照,详细分析了SURF特征点检测算法,并通过实验从特征点提取速度和适应性2个方面对Moravec、Harris、SUSAN、SIFT、SURF等算法进行了比较。结果表明,SURF算法提取影像特征点的速度较快、适应性较强。 Webschemes for scale [14], and in our case, a Harris corner filter [11] to reject edges and provide a reasonable score. Many keypoint detectors include an orientation operator (SIFT and SURF are two prominent examples), but FAST does not. There are various ways to describe the orientation of a keypoint; many of these involve histograms of gradient
