In this work shadow detection and removal process is performed on stereo VHR remote sensing images as a pre-processing stage.
Figure 2 summarizes the main steps of the proposed shadow detection and removal method applied to improve buildings stereo matching process of urban VHR Pairs IKONOS 2 images.
B-Second shadowed pair, the stereo matching process is now applied on the second pair of images; this latter can be considered as one of the most complicated shadowed existing VHR remote sensing pairs.
In This framework the efficient shadows suppression leads to an improvement of stereo matching rate and a considerably reduction of ambiguous regions over the VHR IKONOS2 images.
