WebThe SIFT descriptor still seems to be the most appealing descriptor for prac-tical uses, and hence also the most widely used nowadays. It is distinctive and relatively fast, which is crucial for on-line applications. Recently, Se et al.

And then, you calculate second order derivatives on it (or, the "laplacian"). This locates edges and corners on the image. These edges and corners are good for finding keypoints. But the second order derivative is extremely sensitive to noise.

WebSURF returns almost twice the number of key-points of SIFT, so it is not fair to say SIFT is faster than SURF.
