image mean (help need urgently)

[sasilatha]

hai ,
I need to implement the following formule using matlab

m(x,y) = 1/ Nη Σ (s,t) ε η(x,y) I(s,t)

where η(x,y) is a set of neighbouring pixels centering at (x,y), m(x,y) is the sample mean of I (x,y) and Nη is the size of η.


where I(s,t) may be any pixel in the given image.
I need help to implement the above formula

Hi

your expression is a bit unclear, what is \sum (s,t) \epsilon ? if you are more specific I may help

cheers
