This paper presents an efficient algorithm for post compression optimal rate allocation and packetization within JPEG2000 encoding. JPEG2000, the new ISO/ITU-T standard for still ...
In authentication using watermarking, the original media needs to be slightly modified in order to embed a short media digest in the media itself. Lossless authentication watermar...
One main focus of research in stereo image coding has been disparity estimation, a technique used to reduce the coding rate by taking advantage of the redundancy in a stereo image ...
Coupling the periodic time-invariance of the wavelet transform with the view of thresholding as a projection yields a simple, recursive, wavelet-based technique for denoising sign...

The two major problems raised by a region-based image retrieval system are the automatic definition and description of regions. In this paper we first present a technique of unsup...
Techniques for informationhidinghave become increasingly more sophisticated and widespread. With high-resolution digital images as carriers, detecting hidden messages has become c...
In this paper, a comparison between an objective quality measure and the perceived mean annoyance values of watermarked videos is presented. A psychophysical experiment has been p...
