I have an image that is 11.75x9.5 inches (7084x5676 in pixels). I want to divide the image such that it creates a 1.5x1.5 cropped area. Looks like I have to divide 11.75 by 8 that will be around 1.46 and 9.5 by 6 that will be around 1.58. This is the closest that I can get in order to achieve 1.5x1.5 cropped parts if I want to divide by a whole number. How do I do that in MATLAB? I am confused whether the same number that I used to divide the parameters in inches will be used to divide the parameters in pixels.Secondly, I am confused in generating the for loop so that I will successfully increment the corners of each cropping window in order to cover the entire image area.

See the FAQ:

I'm also attaching some blockproc() demos.
If they don't do what you want, write back.
