This code is an implementation of SURF (Speeded Up Robust Features). SURF will detect landmark points in an image, and describe the points by a vector which is robust against (a little bit) rotation,scaling and noise. It can be used in the same way a

用于图像的特征提取，运算速度快！比传统的SIFT算法快好多！(Feature extraction for images, fast operation! Much faster than the traditional sift algorithm!)
