In this work a new method is proposed for coding artifact reduction of MPEG compressed video sequences. The method makes use of a simple cost-effective technique that allows the b...
This paper presents an error-resilient coding technique combined with error concealment for embedded wavelet coders. The coded images are partitioned into packets and protected by...
In this paper we propose an algorithm to partition MPEG-4 video objects into temporal segments with uniform activity levels. These segments can be used for efficient summarization...
The theoretical foundations of data hiding have been revealed by formulating the problem as message communication over a noisy channel, i.e. the host document. In light of this de...
This paper addresses the problem of to what extent linear transformation can alleviate nonlinear distortion. We investigate a technique of global affine transformation (GAT) corre...
