Abstract:
1. A method, comprising: executing a free viewpoint video synthesis process of video frames starting from source frames belonging to source viewpoints of a scene acquired using a multi-viewpoint camera system, by, defining at least one target virtual viewpoint for the synthesis and computing a corresponding projection matrix for the target virtual viewpoint; computing a corresponding projection matrix for each source viewpoint; projecting pixels of the source frames from the source viewpoints to the target virtual viewpoint as respective contributions to a resulting video frame, wherein the projecting uses the projection matrixes corresponding to the source viewpoints and the target virtual viewpoint; and merging the contributions to the resulting video frame, wherein the contributions include holes due to integer rounding in projecting pixels from the source frames, the method including filling the holes by assigning to a pixel or pixels in a hole an average value of pixels located at two extremities of the hole.
