Hi,
I've been using the function Localmax = imregionalmax(MyMatrix).
The problem is that this function only gives me the local maximums on a neighborhood of 1 pixel, and i need my maximums spaced by 8 pixel horizontally, vertically and diagonally.
Can somebody help me? Thanks in advance.

you can use below command
Localmax = imregionalmax(MyMatrix,conn)
Where "conn" specifies the pixel connectivity.
you can refer to the below documentation link for more information on how to use "conn" property
