3D Photos - Skateboard jump

Depth map obtained with Depth Map Automatic Generator 7 (DMAG7).

What is likely to happen with DMAG7 is that you're gonna have different depths for areas that are of different colors even though they belong to the same object and should be at the same depth. For instance, the right shoe (his right) of the skateboarder: the white Nike swoosh and sole are not at the same depth as the black fabric that makes up most of the shoe. I guess one could play around with the parameters but an easier way albeit manual is to post-process the wrong depths in Gimp. Of course, that kinda defeats the purpose of an automatic depth map generator but I am not sure there's a more efficient way to do it.

Here, I kinda smoothed out the skateboarder and fixed up a few things: the head, the arms, and the space between the legs. Went back and forth between the depth map viewer and the wiggle maker until everything looked kinda reasonable.

A big thank you to Peter Simcoe for providing the stereo pair.


  1. Very good!! A great idea to emphasize the first plane of the head.

    1. Thanks Pepe. Unfortunately, there is still some manual touch-up to do on the depth map but it's much less that it used to be. What are you up to these days? Are you on twitter?
