Low Bandwidth Video Compression with Variable Dimension Vector Quantization
نویسنده
چکیده
This paper presents a new video compression algorithm targeting low bandwidth conversational applications. Based on variable dimension vector quantization, video frames are encoded with variable sized image blocks in a manner which gives precise control over the number of bits assigned to each frame and hence over the transmission delay. This algorithm is compared with an implementation of H.263 for conversational services. The results clearly demonstrate its superiority in minimizing transmission delay while maintaining an image quality comparable to H.263.

A replenishment technique for low bit-rate video compression based on wavelets and vector quantization
This letter presents a variable bit-rate encoding scheme developed for digital video compression based on spatiotemporal decomposition and vector quantization. This encoding scheme exploits the interframe redundancy present in image sequences by employing replenishment of code-vector labels. The experiments indicated that code-vector label replenishment results in a significant reduction of the...
متن کاملVariable Dimension Vector Quantization of Speech Spectra for Low Rate Vocoders
Optimal vector quantization of variable-dimension vectors in principle is feasible by using a set of fixed dimension VQ codebooks. However, for typical applications, such a multi-codebook approach demands a grossly excessive and impractical storage and computational complexity. Efficient quantization of such variable-dimension spectral shape vectors is the most challenging and difficult encodin...

Two VQ algorithms that attempt to use these two aspects are presented: one based on residual vector ...
متن کاملVariable Dimension Weighted Universal Vector Quantization and Noiseless Coding
A new algorithm for variable dimension weighted universal coding is introduced. Combining the multi-codebook system of weighted universal vector quantization (WUVQ), the partitioning technique of variable dimension vector quantization, and the optimal design strategy common to both, variable dimension WUVQ allows mixture sources to be effectively carved into their component subsources, each of ...
