An apparatus for synthesizing texture in a video sequence to be synthesized, the video sequence comprising a sequence of frames, wherein portions of consecutive frames of the video sequence form a spatio-temporal volume to be synthesized, the spatio-temporal volume being spatio-temporally bounded by remaining portions of the video sequence to be synthesized along a boundary of the spatio-temporal volume, the apparatus comprising means for defining a boundary region spatio-temporally extending from the boundary into the remaining portions of the video sequence to be synthesized, means for placing spatio-temporal reference patches in an overlapping manner to fill the spatio-temporal volume to be synthesized such that at least one of the spatio-temporal reference patches overlaps the boundary region and means for applying a graph-cut algorithm to overlapping areas between the spatio-temporal reference patches and the boundary region to yield irregular boundaries between spatio-temporal reference patches in the boundary region to decide which part of the spatio-temporal volume to be synthesized shall be synthesized by which part of the spatio-temporal reference patch and boundary region, respectively, to obtain a synthesized video sequence, the irregular boundaries comprising an irregular boundary extending within an overlapping area of the boundary region, where at least one spatio-temporal reference patch overlaps the boundary region. |
