A Bayesian approach to error concealment in encoded video streams

In ATM networks cell loss causes data to be dropped in the channel. When digital video is transmitted over these networks one must be able to reconstruct the missing data so that the impact of these errors is minimized. In this paper we describe a Bayesian approach to conceal these errors. Assuming that the digital video has been encoded using the MPEG1 or MPEG2 compression scheme, each frame i...

Monitoring Activities from Multiple Video Streams: Establishing a Common Coordinate Frame

Passive monitoring of large sites typically requires coordination between multiple cameras, which in turn requires methods for automatically relating events between distributed cameras. This paper tackles the problem of self-calibration of multiple cameras which are very far apart, using feature correspondences to determine the camera geometry. The key problem is finding such correspondences. S...

Bayesian Biosurveillance Using Multiple Data Streams

Introduction: Emergency Department (ED) records and over-the-counter (OTC) sales data are two of the most commonly used data sources for syndromic surveillance. Most current detection algorithms monitor these data sources separately, and either do not combine them, or combine them in an ad hoc fashion. This paper introduces a causal model that coherently combines the two data sources in order t...

Some extensions and applications of a Bayesian strategy for monitoring multiple outcomes in clinical trials.

We present some practical extensions and applications of a strategy proposed by Thall, Simon and Estey for designing and monitoring single-arm clinical trials with multiple outcomes. We show by application how the strategy may be applied to construct designs for phase IIA activity trials and phase II equivalence trials. We also show how it may be extended to incorporate the use of mixture prior...

Monitoring Multiple Data Streams in Real Time

Online monitoring of data streams poses a challenge in many data-centric applications, such as telecommunications networks, traffic management, trend-related analysis, webclick streams, intrusion detection, and sensor networks. Mining techniques employed in these applications have to be efficient in terms of space usage and per-item processing time while providing a high quality of answers to (...
