How do i find the local maximums of a 2D matrix in a specified neighborhood?

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
