ABSTRACT:
A method for motion tracking and constructing a mosaic of video objects is disclosed. Also disclosed is a method for synthetic object transfiguration from a mosaic. A 2-D triangular mesh is employed to represent a video object, which permits to describe the motion of the object by the displacements of the node points of the mesh, and to describe any intensity variations by the contrast and brightness parameters estimated for each node point. Using the temporal history of the node point locations, the nodes of the 2-D mesh are continued to be tracked even when they become invisible because of self-occlusion or occlusion by another object. By adding new nodes or updating the 2-D triangular mesh, any uncovered parts of the video object are incrementally added to the mosaic. A finite number of views representing the constructed mosaic are selected and used for synthetic transfiguration of a replacement object in place of the original one.
