Fast Background Subtraction from Video Sequences
Journal Title: International Journal on Computer Science and Engineering - Year 2012, Vol 4, Issue 3
Abstract
This paper presents a technique to detect the moving objects quickly and accurately by using a background subtraction algorithm called FaBS (Fast Background Subtraction). The aim of FaBS is to distinguish between moving objects (referred as foreground) from the static one (referred as background) rapidly and efficiently. FaBS constructs for each pixel, a pixel model which is a collection of background samples taken in the past at the same location or in the neighborhood. The pixel model is constructed using the background pixels alone excluding the foreground pixels, if any. The current pixel is classified as foreground or background by comparing it with the corresponding pixel model. Before declaring a pixel as foreground it is passed through a shadow detection mechanism. If it is shadow then the current pixel will be classified as background but this pixel will not be used for updating the pixel model. The pixel model is then updated by using a random policy. Finally, the value of background pixel is propagated into the pixel model of a neighboring pixel. The update algorithm considers the pixels in the neighborhood also thereby exploiting the spatial dependencies. Spatial dependency makes the algorithm robust to camera oscillations. The algorithm relies exclusively on integer computations which makes it suitable for embedded applications.

Cluster Based Message Dissemination for Broadcasting the Emergency/Warning Messages using a Novel Scheduling in VANETS
Vehicular ad hoc networks are a special case of mobile ad hoc networks (MANETs). Unlike MANETs, VANET nodes are moving very fast. It becomes quite challenging to maintain a stable path for broadcasting Emergency and Warn...
