Abstract

This paper presents a low power VLSI architecture for video object motion-tracking that can be used in very low bit rate online video applications. Power has been reduced at both algorithmic and arithmetic levels. The video object motion-tracking architecture consists of two main parts, a mesh-based motion estimation unit and a mesh-based motion compensation unit. The mesh-based motion estimation unit implements parallel block matching motion estimation units to optimize the latency. The mesh-based motion compensation unit uses parallel multiplication-free affine core. The architecture has been prototyped and its performance measures have been evaluated. This processor can be used in online object-based video applications
