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 32x32) and then extract the features from each block?

if true
mat2cell(I,size(I,1)/32*ones(32,1), size(I,2)/32*ones(32,1), 3)
end
This will split an image into 32 x 32 blocks. Then you can extract image features from each blocks using for loop.
