I have divided 3D image size of 240x240x240 by k=4. Thus, I have a total of 60x60x60 patches and each patch have a size of 4x4x4. I would like to find the mean intensity of R G B respectively for each patch (4x4x4) and store it as the voxel value. May I know how do I proceed to do it?
For 2d image, i can use R = image(:,:,1), G = image(:,:,2) and B = image(:,:,3). However, i am not sure how do i do this for a 4x4x4 patch. Can i use the same way to do it?
