An $n$ -dimensional source with memory is observed by notation="LaTeX">$K$ isolated encoders via parallel channels, who compress their observations to transmit the decoder noiseless rate-constrained links while leveraging of past. At ...

I will present an overview on the entropy rate of hidden Markov processes (HMP’s), information and coding-theoretic motivation for its study, and some of its connections to dynamical systems, to non-linear filtering, and to statistical physics. Particular attention will be given to: – Alternative representations: via the Blackwell measure, as a Lyapunov exponent, and as a partition function in ...

In this paper, we present a novel energy compaction method, the selective block reordering, which is used with SPIHT (SBR-SPIHT) coding for low rate video coding to enhance the coding efficiency for motion-compensated residuals. The inter-frame coding basically includes three major parts motion estimation, motion compensation, and motion-compensated residual coding. The motion estimation and ov...

The Block Truncation Coding (BTC) is one of the lossy image compression algorithms. In this paper, we have proposed a method called the Improved Adaptive Block Truncation Coding (IABTC) based on Adaptive Block Truncation Coding (ABTC). The feature of inter-pixel redundancy is exploited to reduce the bit-rate further by retaining the quality of the reconstructed images. The proposed method outpe...
