Separating zoom, rotational and translational motor parameters in image sequences - dividing motion vector data and storing in matrix memory, forming histograms and determining global parameters

摘要

A high definition t.v. transmission system uses separation of zoom, rotation and translation parameters. The first stage in the process consists of storing the motion vectors (Vxi,Vyi) in a memory (A). The values stored are then set in relation to the different coordinates (B) and the different levels in the memory matrix used (C) to generate a 3D histogram (h). Global parameters (axglob,ayglob) are determined (D) for pure translational motion and a separate parameter (rglob) for rotational movement. A global zoom parameter (bglob) is generated by separate units (EFG). ADVANTAGE - Simultaneous generation of zoom, rotation and translational motion.
