1. A method implemented by one or more computing devices, the method comprising: receiving an indication, by the one or more computing devices, of a target region that is to be filled for each of a plurality of stereoscopic images; computing a patch, by the one or more computing devices, to be used to fill the target region in each of the respective stereoscopic images, the computing performed to enforce stereoscopic consistency of the patches for the plurality of stereoscopic images, one to another, through use of a penalty based on stereo mismatches and visual dissimilarity at a relevant disparity between corresponding locations of the plurality of stereoscopic images; and filling the target regions in the respective stereoscopic images, by the one or more computing devices, using the computed patches, respectively.
