A Joint Source - Channel Coding Scheme for RobustImage Transmission Vinay
نویسندگان
چکیده
In this paper we propose a joint source-channel coding scheme for transmission of images over noisy channels. In this scheme, the interaction between the source coding and the channel coding is through a small number of parameters. A robust source coder based on classiication of coeecients of Discrete Wavelet Transform of the image is coupled with a exible error control scheme which uses a bank of channel codes. An iterative algorithm is developed for selection of source coding rates and channel codes. The system has high reliability as the sensitive information is kept small. The developed system has high performance in terms of end-to-end picture quality.

Joint Source-Channel Coding for Progressive Transmission of Embedded Source Coders
We present a scheme for joint source-channel coding for transmission of sources compressed by embedded source coders over a memoryless noisy channel. We nd an exact solution to the problem of optimal channel code allocation. Then we investigate the properties of the solution which allow us to transmit the source progressively while retaining the optimality at intermediate and nal transmission r...
متن کاملAn efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
متن کاملProgressive Image Transmission over Compound Packet Erasure Channels
We consider the problem of joint source-channel coding for progressive packetized transmission of an image over a packet-loss network whose packet loss rate is a random variable. We obtain an algorithm for unequal erasure protection which, by design, maintains progressivity.
متن کاملJoint Source and Channel Coding for Image Transmission Over LossyPacket
We describe a joint source/channel allocation scheme for transmitting images lossily over block erasure channels such as the Internet. The goal is to reduce image transmission latency. Our subband-level and bitplane-level optimization procedures give rise to an embedded channel coding strategy. Source and channel coding bits are allocated in order to minimize an expected distortion measure. Mor...

It has recently been shown that for an image or video transmission scheme to be both eecient and robust in practice that a joint source-channel coding approach is necessary. In this work, we discuss recent eeorts in the eld of joint source-channel coding of images and video. We then present a general methodology for determining the optimal tradeoo between source and channel coding as a function...
