<title>Generalized block-matching motion estimation</title>

Abstract

A general approach to block matching motion estimation is introduced. It very well handles the complex motion found in broadcasting television signals by comparing each block of the current frame with a deformed quadrilateral of the previous one. The calculation of the extra motion information requires additional operations which increase the computational load but the improved prediction reduces the bit rate, especially in scenes with complex motion and deformations of the moving objects.
