The scale invariant Feature Transform (SIFT) are a method to detect distinctive, invariant image Feature points, which easi Ly can is matched between images to perform tasks such as object detection and recognition, or to compute geometrical tran Sformations between images. The Open-source SIFT Library available here's implemented in C using the OpenCV open-source Computer Vision Library and I Ncludes functions for computing SIFT features in images, matching SIFT features between images using Kd-trees, and Computi Ng geometrical image transforms from feature matches using RANSAC. The library also includes functionality to import and work with image features from both David Lowe ' s SIFT executable Andt He Oxford Vgg ' s affine covariant feature detectors. The images below depict some of this functionality.
