Dear all,

I am new IDL user and I need your help in the following question:

I have an image with values between 1 and 8 and I need to create a 5x5
window that will move step by step over each pixel of the image. The
window over each pixel will count how many pixels around the center
pixel have the value 1, 2, 3 ..., or 8.

I do not know how to do that and how can I deal with the pixels on the
boarders of the image because some of the window elements will fall
outside the image.

any help will be appreciated.

thank you,

MD
