How is the edge detection in this video achieved?
Here is the video in question:

I've tried using Canny and Scharr edges to reproduce the effect, but the resulting live feed is very noisy, with hairs coming out of all the edges randomly. I've tried applying a Gaussian filter to the result, but the noise is no where near as low as is shown in the video.
Any ideas?
