MATLAB: How to split the image into blocks and then extract the features from each block

Question

Hello

I extracts image features (invariant moment) using this code

 [filename, pathname] = uigetfile({'*.*';'*.bmp';'*.jpg';'*.gif'}, 'Pick a Degraded Fingerprint Image File');
 im = imread([pathname,filename]);
 figure, imshow(im);title('Fingerprint Image');
 n1=invmoments(im);

How can I split the image into blocks(every block like 32×32) and then extract the features from each block?
