WebJan 13, 2024 · SIFT was first presented in 2004, by David G. Lowe from the University of British Columbia in the paper, Distinctive Image Features from Scale-Invariant Keypoints, This algorithm was patented several years ago, and since then it is included in the non-free module in OpenCV. WebOct 31, 2004 · This paper presents a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene. The features are invariant to image scale and rotation, and are shown to provide robust matching across a substantial range of affine distortion, change in 3D …
WebMar 27, 2024 · This is an implementation of SIFT (David G. Lowe's scale-invariant feature transform) done entirely in Python with the help of NumPy. This implementation is based on OpenCV's implementation and returns OpenCV KeyPoint objects and descriptors, and so can be used as a drop-in replacement for OpenCV SIFT.
