[RESOLVED] reading cell values in an image

[cs_tx_usa]

Hello everyone,

I would be so glad if you could help me on the following problem. I want to read the values of the 8 neighboring cells in an image as shown on the attached file. For example, the green cell is the home cell and it has 8 neighbors (cells from 1 to 8 as seen on the attached image). It will read all 8 neighboring cells then it will move one cell to right (now pixel 4 will be home pixel). Again it will read its neighboring cell values and then it will move to next pixel etc. It will continue till to the end (the last cell or pixel of the image). I would appreciate if you could help me on this..

Thanks in advance.
