Edge Detect image effect adds black edges to the image wherever color differences exceed some threshold.

If more sophisticated geometry-based edge detection is required, the Standard Assets also provide such a normals and depth-based edge detection effect.

As with the other image effects, this effect is only available in Unity Pro and you must have the Pro Standard Assets installed before it becomes available.
