TITLE: FREE SOURCE CODE FOR VIDEO CODEC
(Contributed by Sen-ching Samson Cheung of UCB)
Free source code for a video codec is now available for
downloading from the Video and Image Processing (VIP) Laboratory
in University of California at Berkeley. The URL address is:
CODEC
The source code is for the Matching Pursuit Experimental Video
Codec which is based on the motion-transform hybrid video coding
framework commonly employed in standard based system such as
H.263 and MPEG2. Matching pursuit (MP) is an over-complete
expansion technique that can be used in place of the DCT for
prediction error coding after motion compensation.
The objective of making this package freely available is to
stimulate further research activities in the area of MP video
coding. Thus, our programs are geared towards clarity and are not
fully optimized. The skeleton of the programs is based on the
freely available H.263 TMN coder version 2.0 from Telenor R&D.
This package includes both an encoder and a decoder. The encoder
can take QCIF, CIF or SIF size yuv-concatenated sequences as
input. It supports simple scene-change detection and various
kinds of simple rate control. The package has been tested on
Solaris 2.5.1, HP-UX 10.01, Window 95 and Window NT systems.
