چکیده
This paper presents a low power VLSI architecture for video object motion-tracking that can be used in v e v 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 afJine core. The architecture has been protoQped and its pe$ormance measures have been evaluated. This processor can be used in online objectbased video applications.

متن کاملAlgorithm-based low-power VLSI architecture for 2D mesh video-object motion tracking
This paper presents an algorithm-based low-power VLSI architecture for video object (VO) motion tracking. The new architecture uses a novel hierarchical adaptive structured mesh topology. The structured mesh offers a significant reduction in the number of bits that describe the mesh topology. The motion of the mesh nodes represents the deformation of the VO. The motion compensation is performed...

In this paper, we propose a new full-fuzzy video ratecontrol algorithm (RCA) for variable bit rate (VBR) videoapplications. The proposed RCA provides high qualitycompressed video with a low degree computational complexity.By controlling the quantization parameter (QP) on a picturebasis, it produces VBR video bit streams. The proposed RCAhas been implemented on the JM H.264/AVC video codec andth...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
متن کاملCoding Face at Very Low Bit Rate via Visual Face Tracking
Facial expressions convey very important information which is sometimes indispensable for people to fully understand the speech during communication. When the volume of video data is overwhelming and channel resources are limited, very low bit rate video coding becomes a solution for teleconferencing. In this paper, we propose an efficient and robust very low bit rate face coding method via vis...
