WebJan 8, 2013 · In 2004, D.Lowe, University of British Columbia, came up with a new algorithm, Scale Invariant Feature Transform (SIFT) in his paper, Distinctive Image Features from Scale-Invariant Keypoints, which extract keypoints and compute its descriptors.*(This paper is easy to understand and considered to be best material available on SIFT. This explanation … WebFeb 3, 2024 · In 2D images, we can detect the Interest Points using the local maxima/minima in Scale Space of Laplacian of Gaussian. A potential SIFT interest point is determined for a given sigma value by picking the potential interest point and considering the pixels in the level above (with higher sigma), the same level, and the level below (with lower sigma …
