WebFeb 20, 2015 · Using SIFT there are 2 steps you need to perform in general. Extract SIFT features. These points (first output argument of size NPx2 (x,y) of your function) are scale invariant, and should in theory be present in each different image of the same object. This is not completely true. Often points are unique to each frame (image). cryptpad review https://mertonhouse.net
