streams. Error concealment by postprocessing refers to operations at the decoder to recover the damaged areas based on characteristics of image and video signals. Finally, interactive error concealment covers techniques that are dependent on a dialog between the source and destination. Both current

Preliminary communication Inclusion of the latest research work to a real life applications and achieving adaptive video signal post-processing is a complex and timely task. The proposed framework breaks the filtering process into several distinct phases and enables a researcher to move at a faster

Multiresolution image and video coding schemes o er both excellent coding e ciency and the ability to support scalability. This paper gives an introduction to the principles of multiresolution coding of image and video signals. Besides critically sampled subband pyramids, oversampled pyramid

The Shannon/Nyquist sampling theorem tells us that in order to not lose information when uniformly sampling a signal we must sample at least two times faster than its bandwidth. In many applications, including digital image and video cameras, the Nyquist rate can be so high that we end up with too

technique to avoid human monitoring and automate the video surveillance system. This system avoids the need to have a background image of the traffic. To a given input video signals, frames are extracted. Selected frames are used to estimate the background. This background image is subtracted from each

This paper presents a secure (tamper-resistant) algorithm for watermarking images, and a methodology for digital watermarking that may be generalized to audio, video, and multimedia data. We advocate that a watermark should be constructed as an independent and identically distributed (i

We present an object recognition system based on the Dynamic Link Architecture, which is an extension to classical Artificial Neural Networks. The Dynamic Link Architecture ex-ploits correlations in the fine-scale temporal structure of cellular signals in order to group neurons dynamically

with a layered transmission system. By selectively forwarding subsets of layers at constrained network links, each user receives the best quality signal that the network can deliver. We and others have proposed that selective-forwarding be carried out using multiple IP-Multicast groups where each

We consider the problem of memory allocation for intermediate data in the mapping of video algorithms onto programmable video signal processors. The corresponding delay management problem is proved to be NP-hard. We present a solution strategy that decomposes the delay management problem into a
