MATLAB: How to divide an image into 16×16 non overlapping blocks

Question

how to divide an image into 16×16 non overlapping blocks for finding the local binary pattern in the further steps

Answer 1

Hello,

Assuming your image has size m x n where m and n are multiples of 16:

YourImage = im2double(YourImage);
[m,n] = size(YourImage);
Blocks = cell(m/16,n/16);
counti = 0;
for i = 1:16:m-15
   counti = counti + 1;
   countj = 0;
   for j = 1:16:n-15
        countj = countj + 1;
        Blocks{counti,countj} = YourImage(i:i+15,j:j+15);
   end
end

You can access the blocks by calling Blocks{i,j}.

Hope this helps!
