A comparison between DMAG5 and DMAG6, two (free) automatic depth map generators.
DMAG5 is a local window based automatic depth map generator while DMAG6 uses a global method based on Belief Propagation (BP). Kinda cool to see that the end result is about the same. DMAG5 and DMAG6 can both be downloaded from http://3dstereophoto.blogspot.com.
