An implementation of SIFT detector and descriptor
This code creates a SIFT (Scale-Invariant Feature Transform) descriptor object using the xfeatures2d module of OpenCV. SIFT is a popular feature detection and extraction algorithm used in computer vision and image processing tasks. The SIFT descriptor creates a set of distinctive, invariant feature points in an image that can be used for tasks such as object recognition, image stitching, and 3D reconstruction. The .create() method initializes the SIFT descriptor object with default parameters.
