Claim:
1. A method for determining a disparity value for an object located in or to be placed into a stereoscopic image pair, the stereoscopic image pair having an associated disparity map having disparity estimates for individual pixels of the stereoscopic image pair, the method comprising: determining an area to be analyzed in one of the stereoscopic images; retrieving those disparity estimates from the associated disparity map that are associated with pixels of the stereoscopic image pair that lie within the determined area; building a histogram from the retrieved disparity estimates; searching a contiguous range of histogram bins, each histogram bin of the contiguous range containing at least a specified minimum number of disparity estimates and the contiguous range containing in total at least a specified number of disparity estimates; and selecting a disparity estimate for the determined area from the contiguous range of histogram bins.
