I tried to extract the zernik shape feature from my croped image(nput image attached) and got the following error . i think this error due to different scaling of rows and columns (146x107x3).

Index exceeds matrix dimensions.

Error in Zernikmoment (line 28)

Product = p(x,y).*Rad.*exp(-1i*m*Theta);
