WebThe scale-invariant feature transform (SIFT) is a computer vision algorithm to detect, describe, and match local features in images, ... In addition, features are created from a … WebFinally, the SIFT algorithm normalizes the feature descriptor for rotation. It finds the dominant gradient direction in the patch around the key point and shfits the gradient histograms such that the first orientation bin corresponds to that direction. This makes the descriptors invariant to in-plane rotation.
