Stereo as energy minimization
Expressing this mathematically
1.Match quality
–Want
each pixel to find a good match in the other image
2.Smoothness
–If two
pixels are adjacent, they should (usually) move about the
same amount
We want to minimize
•This is a special type of energy
function known as an
MRF (Markov Random Field)

and fast algorithms have been recently developed:
