Abstract:
1. A method of up-converting a frame rate of a digital video signal, the method comprising: receiving a digital video signal containing a plurality of temporally spaced apart image frames in one view of a multiview set, the plurality of temporally spaced apart image frames include two consecutive frames comprising a first frame and a second frame; finding in one of the received frames, a match for an object in the other of the received frames; utilizing three-dimensional (3D) data in respect of the matched object within the received frames to determine 3D movement matrices for the matched object; using the 3D movement matrices, determining a temporally intermediate 3D position of the matched object with respect to the received frames to enable an interpolated frame to be generated temporally between the first and second frame; and projecting the 3D position of the matched object onto any two-dimensional view of the multiview set to thereby generate the interpolated frame at a desired time instant and view; wherein finding a match for an object comprises segmenting a moving object by obtaining the differences between the two consecutive frames by calculating pixel-wise absolute differences between depth, D, and texture, C, frames at time instants t and t+1: and using these frames calculating a global segmentation map.
