My question is related with above link.
I want to replace the center pixel of a 3x3 window filter with the average of four neighbour pixels in 3 x 3 neighbourhood.
Can anyone modify code provided on that link..?

Nimisha - which four of the 3x3 neighbourhood do you wish to average? The ones at the north, south, east, and west of the centre pixel?

Just convolve your data with the filter
F = [0 1 0; 1 0 1; 0 1 0]/4;
You can use imfilter for the convolution.

The error message is telling you that your inputs to conv must be vectors. You are passing matrices. Try using conv2 instead.
