Rate-Distortion Performance for Joint Source and Channel ...
in image coding [9] and have demonstrated superior performance, both subjectively and objectively and for both low and high degrees of compression, we will combine this technique with two different scalar quantization schemes to build a base for optimizing the rate-distortion behavior of the joint source and channel coders....
Robust transform image coder over noisy channel | Request PDF
A combined source-channel coding approach is described for the encoding, transmission, and remote reconstruction of image data. Several two dimensional image source encoding schemes are considered.
 JOINT SOURCE/CHANNEL CODING FOR MULTIPLE SOURCES TRANSMISSION
However, these schemes do not take channel coding into account. In [1], a practical joint source/channel coding algorithm based on scalable source coders was proposed for the transmission of multiple images sharing a common channel. It effectively minimizes the expected distortion over all reconstructed images at the receiver end within a given...
Joint Source-Channel Coding of GGD Sources with Allpass ...
Keywords: J oint source-channel coding; source reshaping; bit allocation. 1. INTRODUCTION In an end-to-end communication system designed for image or video over noisy channels, the encoder usually consists of a source coder and a channel coder. The source coder, typically including transform, quantization and entropy coding, is to...
