In this paper a new non-predictive wavelet based video coding scheme is presented. The scheme omits motion estimation/compensation process (prediction step) in the temporal axis. The video sequence is grouped into a number of frames. An adaptive thresholding algorithm is used to optimize the subband threshold settings, and use to identify the significance of the subband coefficients. The significant...
Sprite generation is extensively used for the video compression. Real time efficient video analytics (VA) for surveillance system need to make decision with in camera processing unit or at camera edge processing unit. The Video Analytics is required to work on good resolution footage to register tiny but important information that may otherwise be lost during subsequent compression process, especially...
A multiple camera surveillance system is typical example of a Distributed Video (DV) system with many-to-one topology which demands the use of new paradigm with multiple encoders, installed at number of locations and very few decoders in a control room. This paradigm open- up new frontiers for the research community in designing low cost encoders even at the cost of expensive decoders. A solution...
In this paper a new non-predictive video codec for mobile applications is presented. The non-predictive scheme omits prediction step in the temporal axis. Hence, it increases robustness for transmission at low bit rate in mobile channel. The video sequence is grouped into a number of frames (GOP) and the same subband from each frame in the GOP are joined together to exploit their spatial-temporal...
