We describe a steganographic system which embeds secret messages into a video stream. We examine the signal path which typically includes discrete cosine transformation (DCT) based...
We have proposed a novel model-based compression technique for nonstationary landmark shape data extracted from video sequences. The main goal is to develop a technique for the co...
A novel motion activity descriptor and its extraction from a compressed MPEG (MPEG-1/2) video stream are presented. The descriptor consists of two parts, a temporal descriptor and ...
This report describes a pay broadcasting system for the Internet. This system would enable tens of thousands of people to access an identical video stream simultaneously. In this ...
Nonlinear image reconstruction based upon sparse representations of images has recently received widespread attention with the emerging framework of compressed sensing (CS). This ...
