Localization of tampering in contrast and brightness adjusted images using distributed source coding and expectation maximizatio
Media authentication and tampering localization are important in content delivery via untrusted intermediaries, such as peer-to-peer (P2P) file sharing. Many differently encoded v...

Modelling of distortion caused by packet losses in video transport
Abstract— This paper analyzes transmission-error induced distortion in decoded video. A recursion model is derived that relates the distortion in successive P-frames. The model t...
