Detect or Track: Towards Cost-Effective Video Object Detection/Tracking

Using Histograms to Detect and Track Objects in Color Video

Track-before-detect procedures for detection of extended object

In this article, we present a particle filter (PF)-based track-before-detect (PF TBD) procedure for detection of extended objects whose shape is modeled by an ellipse. By incorporating of an existence variable and the target shape parameters into the state vector, the proposed algorithm performs joint estimation of the target presence/ absence, trajectory and shape parameters under unknown nuis...

Algorithms for Cost-Effective Video Compression

The volumes and costs of video storage and transmission are soaring. This situation can only be ameliorated by massive investments in infrastructure or by technological breakthroughs or both. This paper presents one such technological breakthrough that can reduce the size of any video file compressed by any existing video codec, e.g., MPEG-4, H.264, DivX, VC-1, etc., to between 25% and 10% of s...

Cost Effective and Scalable Video Streaming Techniques

Video on demand (VOD) is a key technology for many important applications such as home entertainment, digital libraries, electronic commerce, and distance learning. A VOD system allows geographically distributed users to play back any video from a large collection stored on one or more servers. Such a system may also support VCR-like interactions such as fast forward, fast rewind, jump forward,...
