For each pixel in a cell, compare the pixel to each of its 8 neighbors (on its left-top, left-middle, left-bottom, right-top, etc.). Follow the pixels along a circle, i.e. clockwise or counter-clockwise.

Where the center pixel s value is greater than the neighbor s value, write 1 . Otherwise, write 0 . This gives an 8-digit binary number (which is usually converted to decimal for convenie-matlab vide the examined window into cells (e.g. 16x16 pixels for each cell).
