Low-complexity Big Video Data Recording Algorithms for Urban Surveillance Systems

چکیده
Big Video data analytics and processing are becoming increasingly important research areas because of infinite generation of massive video data volumes all over the world. In this paper, by utilizing Bayesianbased importance analysis, we propose a set of novel, simple but effective video recording methodologies and intelligent algorithms to solve the so-called big video data volume problem in urban surveillance systems. The complexity of our proposed algorithms are only O(n), hence they can be easily implemented in real video urban surveillance systems without complicated computational cost. The simulation results show amazing recording efficiency. Our methods can dramatically reduce the hard discs (HD) occupation space requirement so that the recording time of HDs can be greatly enlarged.

Fire detection using video sequences in urban out-door environment
Nowadays automated early warning systems are essential in human life. One of these systems is fire detection which plays an important role in surveillance and security systems because the fire can spread quickly and cause great damage to an area. Traditional fire detection methods usually are based on smoke and temperature detectors (sensors). These methods cannot work properly in large space a...

The Urban Surveillance Systems generate huge amount of video and image data and impose high pressure onto the recording disks. It is obvious that the research of video is a key point of big data research areas. Since videos are composed of images, the degree and efficiency of image compression are of great importance. Although the DCT based JPEG standard are widely used, it encounters insurmoun...
