why Invariant moments are slightly diffident for the same image
it is mentioned as Hu-moments are invariant from scale, rotation and orientation. But when i compared the Hu-moments by using same image with different sizes, i got slightly different values.
i get image with 100,75(height,width) at first time and then same image with 200,150(height, width) at second time.
can someone explain the reason for that? plz help.
thank you
