Stereo Conversion - Harrison Ford in Raiders of the Lost Ark

The process of converting a 2d image into a 3d image always starts with a 2d image and a sparse depth map (painted in Gimp or Photoshop).

In the following, I am gonna show depth maps generated by DMAG4 using 1 scale and 3 scales. Note that the more scales you use, the slower DMAG4 runs but the fewer iterations needed.

Clearly, the depth map obtained using 3 scales is better than the one obtained using 1 scale. At this point, it's not a bad idea to smooth the depth map while preserving the edges using, for instance, EPS9.

DMAG4 and EPS9 are available at 3D Software. WiggleMaker is WiggleMaker.
