You asked if you could benefit from what I did for the other person. Please be assured that the answer is NO.
I will not be able to answer further questions as to what I did or did not tell someone else.

I'd start with my shrinkWrap function to segment the hand.

It looks tough because even I can't say where the veins are. Even if I could, it's definitely a judgment call as to when the vein disappears. You might start off looking for algorithms here: http://iris.usc.edu/Vision-Notes/bibliography/contentsmedical.html#Medical%20Applications,%20CAT,%20MRI,%20Ultrasound,%20Heart%20Models,%20Brain%20Models
