WebThe seminal paper introducing SIFT [Lowe 1999] has sparked an explosion of local keypoints detector/descriptors seeking discrimination and invariance to a specific group of image transformations [Tuytelaars and Mikolajczyk 2008]. SURF [Bay et al. 2006b], Harris and Hessian based detectors [Mikolajczyk et al. 2005], MOPS [Brown et al. 2005], WebSep 24, 2024 · The scale-invariant feature transform (SIFT) is an algorithm used to detect and describe local features in digital images. It locates certain key points and then furnishes them with quantitative information (so-called descriptors) which can for example be used for object recognition. The descriptors are supposed to be invariant against various …
