Two function files that can be applied on an image to calculate the seven invariant moments defined by Hu(1962)in terms of centralized Moments for purpose of shape recognition . The function to be used directly by the user is
feature_vec(A),where A is a 2D matrix representing an image.
Inside this function another function :cent_moment(p,q,A)is called to calculate the normalized central moments
You can use it in separate.But you don't need to do so when using feature_vec(A)
Attached with the two functions is a pdf file containing short mathematical notes about the theory of Invariant Moments.
