I extracted several points (x,y-coordinates) of interest from my image using OpenCV in Python (i.e. Thresholding, contourfinding, moments). Now, I want to match those points with a reference pattern to exclude falsy detected points. My approach is to match the features/descriptors from the image points with the features/descriptors of the reference pattern, but I don't know how to extract features/descriptors from the image points.
How do I extract features/descriptors from the given coordinates using OpenCV in Python?
