You take an image, and blur it a little. 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. dichloromethane atmospheric lifetimeWebThe SIFT algorithm was introduced by David G.
