Thank you Bruno
can I ask one more question?
how to make this silide window with function
say i ineed to calculate local variance for every pixel in a window of 2*2 by this equation
where i,j is the pixel location in the window & x,y is the loop on all pixel in the image and the sum is done over y&x & I is the pixel value
E(i,j) = sum (var( I(1+y + i/2^2 , 1 +x + j/2^2) ))
