Hi there, I would need to create a function that tells me whether a
set of pixels (given by their 2D coordinates) forms a single blob or
consists of two or more disjoint groups, in either a 4- or 8-
neighborhood. Can anyone suggest a computationally cheap method for
doing that (i.e., one that doesn't rely on label_region or search_2d)?
Thanks!

Guillermo
