Proceedings ArticleDOI
Robust image transmission using a new joint source channel coding algorithm and dual adaptive OFDM
TL;DR: A novel and analytically based joint source channel coding (JSCC) algorithm to assign unequal error protection (UEP) in a way to minimize the expected mean square error (MSE) at the receiver while minimizing the probability of catastrophic failure.
Journal ArticleDOI
Information-theoretic performance of quadrature mirror filters
A. Divakaran,William A. Pearlman +1 more
TL;DR: This work uses the closed-form expressions to derive the relationship between information-theoretic loss and the frequency selectivity of the QMF, by calculating first-order entropy as well as rate-distortion theoretic performance of a two band QMF system.
Proceedings ArticleDOI
Integrated lossy, near-lossless, and lossless compression of medical volumetric data
TL;DR: A simple and practical method to estimate online the optimal bit rate and provide a theoretical justification for it is proposed and shows that the proposed scheme provides improved, embedded lossy, and lossless performance competitive with the best results published so far in the literature.
Proceedings ArticleDOI
Progressive resolution coding of hyperspectral imagery featuring region of interest access
Xiaoli Tang,William A. Pearlman +1 more
TL;DR: This work proposes resolution progressive Three-Dimensional Set Partitioned Embedded bloCK (3D-SPECK), an embedded wavelet based algorithm for hyperspectral image compression that also supports random Region-Of-Interest (ROI) access.
