I would like to thankx you for your quick response
Actually I would like to do the following step to this image size for example (700X314 Pixel), using the matlab code: 1- How to divide the image to (4X12 part equally), Row X Colum. 2- How to show these part (corners, center, from the 48 parts of the image which has been divided in the first step ). 3- How to get the matrix of each part of the image (48 divided parts).
