Sift descriptor matching
The SIFT-Rank descriptor was shown to improve the performance of the standard SIFT descriptor for affine feature matching. A SIFT-Rank descriptor is generated from a standard SIFT descriptor, by setting each histogram bin to its rank in a sorted array of bins. See more The scale-invariant feature transform (SIFT) is a computer vision algorithm to detect, describe, and match local features in images, invented by David Lowe in 1999. Applications include object recognition, robotic mapping and … See more For any object in an image, interesting points on the object can be extracted to provide a "feature description" of the object. This description, extracted from a training image, can … See more Scale-space extrema detection We begin by detecting points of interest, which are termed keypoints in the SIFT framework.
