T. Aach et A. Kaup, DISPARITY-BASED SEGMENTATION OF STEREOSCOPIC FOREGROUND BACKGROUND IMAGE SEQUENCES, IEEE transactions on communications, 42(2-4), 1994, pp. 673-679
In this contribution, we describe a method for displacement estimation
in stereoscopic images, which is closely coupled with a segmentation
of the pictures into homogeneously displaced regions. The technique is
driven by a statistical optimization criterion which assesses the qua
lity of the disparity estimate and of the segmentation, thus improving
both of these simultaneously. In addition, the optimization criterion
explicitly takes occluded areas into consideration. With the addition
al help of two constraints, this enables the algorithm to locate regio
ns corresponding to occlusions accurately.
