2D to 3D Conversion - Marilyn holding a rose

Here's a 2d to 3d image conversion made with Depth Map Automatic Generator 4 (DMAG4). The photo was taken by Sam Shaw, movie star photographer.

3d animated gif obtained with Wiggle Maker.

My workflow of converting a 2d image into a 3d image is as follows: 1) Use Gimp pencil tool, eraser tool, selection tool, and gradient tool to scribble depth cues on what I call the sparse depth map, 2) run DMAG4 on that sparse depth map to get a dense depth map, 3) load up the 2d image and dense depth map into Wiggle Maker and make note of areas that don't wiggle correctly, 4) go back to Gimp to fine tune the sparse depth map, and 5) go back to step 2. I do this until I am happy with the animation.
