2D image recognition tool

Hey y'all,
this is a UV Wrap from blender:
http://www.pyroteknots.com/pix/blender/grid.jpg
I am looking for a tool or API that can identify intersections in a
grid like this. Actually, I want a tool that can take an image like
this and morph another 2D image onto it in a weighted deformation. I
figure I will have to write the second one.
Thanx!

Dunno' about the rest of it, but just thought I'd comment
the author of that image has no idea of the advantages and
disadavantages of particular image formats.

A 'black and white line trace' image is well suited to being
16(*) color and GIF or PNG, rather than JPG.

The 220 Kb JPEG reduces to a 46Kb (16 color) GIF.

* Or even '2 color'.

I don't know if you'll find an off-the-shelf solution. There are some
published algorithms, though. See
