From: Sonia Rauf on 2 Mar 2010 07:31 I am working on extraction of blood vessels from MRA images. In order to find 8-connected neighbors in binary image bwlabel function is used. How can we find 8-connected neighbors of gray scale image.

How can we find 8-connected neighbors of gray scale image. --------------------------------------------------------------- Every pixel in a 2D image (except pixels at the edges) has 8 neighbors.
