ABSTRACT
This paper describes a methodology for using the matrix-vector multiply and scan conversion hardware present in many graphics workstations to rapidly approximate the optical flow in a scene. The optical flow is a 2-dimensional vector field describing the on-screen motion of each pixel. An application of the optical flow to MPEG compression is described which results in improved compression with minimal overhead.

MPEG-4 to H.264/AVC transcoding
IWCMC '07: Proceedings of the 2007 international conference on Wireless communications and mobile computingIn this paper, we consider the problem of MPEG-4 visual simple profile to H.264/AVC baseline profile (BP) transcoding. An efficient transcoding algorithm with fast mode selection and motion vector refinement is proposed. The proposed algorithm exploits ...
MPEG Unified Speech and Audio Coding
The MPEG Audio Subgroup has a rich history of accomplishments in creating music coding technology. At higher bit rates, MPEG technology can represent arbitrary sounds, including the human voice, with excellent quality. MPEG-1 and MPEG-2 Audio coders use ...
No-reference analysis of decoded MPEG images for PSNR estimation and post-processing
We propose no-reference analysis and processing of DCT (Discrete Cosine Transform) coded images based on estimation of selected MPEG parameters from the decoded video. The goal is to assess MPEG video quality and perform post-processing without access ...
