Performance of JPEG Image Transmission Using Proposed Asymmetric Turbo Code

Research on Unequal Error Protection with Punctured Turbo Codes in Jpeg Image Transmission System

An investigation of Unequal Error Protection (UEP) methods applied to JPEG image transmission using turbo codes is presented. The JPEG image is partitioned into two groups, i.e., DC components and AC components according to their respective sensitivity to channel noise. The highly sensitive DC components are better protected with a lower coding rate, while the less sensitive AC components use a...

Error Resilient Image Transmission over Wireless Fading Channels

Nowadays transferring images and video over wireless channels is becoming more use of the medium. However, a wireless medium is not very reliable in the way that it adds unwanted components and noise to the wireless transmission. So there may be a loss of data. Due to this possible loss of data without the capability of resending a correct version we need a system to protect and correct such lo...

Image Watermarking Based on 5/3 Wavelet Decomposition and Turbo-Code

This paper is an attempt to describe a new scheme of image watermarking based on 5/3 wavelet decomposition and turbo-code. This new watermarking algorithm based on embedding mark (signature) in the multi-resolution field. For the purpose of increasing the image watermarking robustness against attacks of an image transmission, we encode with a turbo code an image-embedded mark. This new scheme o...
