## Computer Vision: SIFT algorithm (Scale Invariant Feature Transform) Elegant object matching from several viewpoints ## Introduction SIFT is one of the most widely known algorithms in computer vision. Its core objective consists of detecting object keypoints, generating descriptors for them, and matching the same objects across images. As the name suggests, SIFT is a scale-invariant algorithm, meaning that the same object can appear at different scales in a pair of images, and SIFT will still be able to successfully detect its keypoints. In addition, SIFT is rotation-invariant, making…
