| Abstract | Over the past decade, the realistic visual communication systems have been
dramatically grown and have been useful for various purposes. So far, however, the
amount of information of a three-dimensional imaging system has limited many
commercial applications, since this system results in a two fold increase in bandwidth over
the existing monoscopic channel bandwidth. Thus, the efficient compression algorithms
are vital to reduce the size of data without sacrificing the perceived quality.
This thesis has been set to develop a framework for stereo video compression by
exploiting spatial correlation, temporal correlation and high correlation between stereo
image pair in order to increase the quality of stereo video at the specific bit rate with the
Embedded Block Coding with Optimized Truncation (EBCOT) coding. The proposed
stereo video codec is composed of two sub-codecs for coding and decoding two image
streams, namely the main stream that independently coded by an EBCOT video codec and,
secondly, the auxiliary stream that is predicted based on disparity compensation and coded
the residual frames.
The experimental results of comparing the performance of the proposed codec with
the DCT based stereo video codec and ZTE based stereo video codec show outperforms in
coding both main and auxiliary streams. Apart from the significant PSNR gain, proposed
codec has various other advantages such as easier to control the desired size, SNR
scalability, resolution scalability, smaller buffer need, random access capability and good
error resilience. Therefore, the EBCOT based stereoscopic video codec is highly attractive
for the next generation of multimedia communications. |
