Abstract

A new multivector motion estimation and compensation strategy particularly suitable for region-based coding strategies is introduced. Region motion is described through a variable number of motion vectors applied to specific region control points. Motion estimation is carried out applying locally translational models to the control points, while more complex region motion models are used for compensation. No information about this control points is required to be transmitted,d as their determination is based on information available at the decoder. The application of this strategy within the context of a region-based hybrid video codec operating on arbitrary shaped regions where efficiency is improved eliminating the transmission of any image regions description is presented. Results showing very good quality images at transmission bit rates in the order of 40 kb/s are presented.
