LiveVideo: Real-time Video Analysis Software

Image
The LiveVideo , an open-source real-time object detection and tracking software for H.264/AVC videos, was released. It enables us to effectively detect and track multiple objects in real time in H.264|AVC bitstreams with static background by applying probabilistic spatiotemporal macroblock filtering (PSMF) and partial decoding technique. This software exhibits reliable performance in a variety of natural scenes with static background as well as fast computation time (30~50 frames/sec) enough to be performed in real-time. You can freely download its source codes from the Sourceforge project . To quickly study the usage of this software and to understand the structure of source codes, you can refer to the Tutorial document . To figure out theoretical backgrounds, visit the homepage of the corresponding research project and read its relevant papers: SPIE 2009 and LNCS 2007 . Also, the Wiki site of LiveVideo will provide you useful information. If you need techni...

Fractal Dynamics in the Resting Brain

Image
In this talk, we address two issues on (1) how to apply fractal theories to the functional connectivity analysis of the brain, and (2) to introduce the concept of fractal connectivity as the convergence of wavelet correlation in long memory processes.
