WebSIFT is proposed by David G. Lowe in his paper. ( This paper is easy to understand, I recommend you to have a look at it ). In general, SIFT algorithm can be decomposed into … WebThe Laplacian of Gaussian (LoG) operation goes like this. 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.

"WebScale-invariant feature transform (SIFT) is a method that was described by David G. Lowe in 1999 . It is used to extract features invariant in orientation and scale in images. This approach transforms an image into a large number of local feature vectors, each of which is invariant to translation, scale or size, illumination, and image rotation. " - Sift david g.lowe
