Reuse of Motion Processing for Camera Stabilization and Video Coding
The low bit rate of existing video encoders relies heavily on the accuracy of estimating actual motion in the input video sequence. In this paper, we propose a Video Stabilization...

Low-power log-MAP turbo decoding based on reduced metric memory access
Due to the powerful error correcting performance, turbo codes have been adopted in many wireless communication standards. Although several low-power techniques have been proposed,...

An Illumination Invariant 3D Model Based Tracking Algorithm, with Application in Video Compression
We present an algorithm for illumination invariant 3D model based tracking and video compression. While model-based coding schemes are well developed, the compression rate reduces...

Globally Optimal Uneven Error-Protected Packetization of Scalable Code Streams
In this paper, we present a family of new algorithms for rate-fidelity optimal packetization of scalable source bit streams with uneven error protection. In the most general settin...

Mixed-resolution distributed video codec without motion estimation at the encoder
Inspired by recent results showing that Wyner-Ziv coding using a combination of source and channel coding may be more efficient than pure channel coding, we have applied coset cod...
