Turbo Source Compression with Jointly Optimized Inner Irregular and Outer Irregular Codes
—In this paper, we present a near-lossless compression scheme for scalar-quantized source codec parameters based on iterative source-channel decoding (ISCD). The scheme is compar...

3-D Scalable Medical Image Compression With Optimized Volume of Interest Coding
We present a novel 3-D scalable compression method for medical images with optimized volume of interest (VOI) coding. The method is presented within the framework of interactive te...

Polar codes are optimal for lossy source coding
We consider lossy source compression of a binary symmetric source using polar codes and the low-complexity successive encoding algorithm. It was recently shown by Arikan that polar...

Compression-Aware Energy Optimization for Video Decoding Systems With Passive Power
The objective of dynamic voltage scaling (DVS) is to adapt the frequency and voltage for configurable platforms to obtain energy savings. DVS is especially attractive for video dec...
