abSIRD for Matlab

Converts a depth-map into a random dot autostereogram.

This function interprets imageData as a height-map and converts it to a random dot stereogram. A random dot stereogram is an image that can be perceived as 3-dimensional by viewing it in the proper way. For more information on random dot sterograms, see http://en.wikipedia.org/wiki/Autostereogram

The algorithm used is abSIRD, published in 2004 by Lewey Geselowitz. It is a fast, in-place algorithm that is exquisitely simple to implement.
