For the spare depth map, I used a gradient over the whole image which I then erase to reveal the main subject. Then, I drew as little as possible to suggest the depths on the main subject.
To draw the edge image, I simply used the "Paths Tool" left-clicking all along the main subject.
I used:
beta = 10
number of iterations = 5000
scale number = 1
connection level = 1
connection level 2 = 1
Because I used an "edge image" which prevents bleeding across object boundaries, I was able to use a relatively low value for beta to facilitate depth propagation.
To create a wobble/wiggle, you may also want to use FSG11. The cool thing about FSG11 is that you can provide the background that's gonna be revealed when creating the frames in the form of a second reference image and depth map.
To create the second reference image, I just took the reference image and use the cloning tool to extend the background into the main subject.
The second reference depth map is the gradient that I used to create the sparse depth map.
Here's a video tutorial for the whole thing:
