Analysis of stereoscopic images

A non-transitory computer program product adapted to implement a method of processing in an image processor a pair of images intended for stereoscopic presentation to identify left-eye and right-eye images of the pair, the method comprising dividing both images of the pair into a plurality of like image regions;

• determining for each region a disparity value between the images of the pair to produce a set of disparity values for the image pair;
• deriving for each region a confidence factor for the measure of disparity;
• determining a correlation parameter between the set of disparity values and a corresponding set of disparity values from a disparity model, in which the contribution of the disparity value for a region to the said correlation parameter is weighted in dependence on the confidence factor for that region;
• and identifying from said correlation parameter the left-eye and right-eye images of the pair, wherein the left eye and right eye images form a stereoscopic pair.
