Extracting landmarks from 3D body scan

The textures attached to 3D scans of the body sometimes have white dots to mark specific landmarks. I’m trying to figure out the best way to automatically pick these up. I figure a bit of image processing on the texture file looking for white dots.

Say I have a wrl file with a texture. How could I get access to the image file for the texture and then how does this match up with the 3D model?

Thanks,
Sam

Sam, can you post, or send me via private message, a simple example?
