In the following code image was divided into 8 * 8 blocks
Image=rgb2gray(imread('1.jpg')); [m n]=size(Image);
Nbrx = floor(m./8); Nbry = floor(n./8); Nd=1;
for i=1:Nbrx
for j=1:Nbry
Mat=Image((i-1)*8+1:i*8,(j-1)*8+1:j*8);
subplot(Nbrx,Nbry,Nd); imshow(Mat)
Nd=Nd+1;
end
end
How can we apply the standard deviation on each block

It operates given function on an image block by block, so will get rid of the code you wrote above to partition the image. And std gives standard deviation.
