Simple depth estimation from stereo images

Disparity is estimated using the normalized cross-correlation on a pair of uncalibrated stereo images. The cross-correlation is realized with a neighborhood of 11x11 pixels. Disparity is extracted by fitting a 2nd order polynomial around the maximal correlation using a search range of -40..40 pixels. The resulting disparity is filtered with a medianfilter using a 35x35 neighborhood.
