Study on Section Video Transmission with Preset Background of Vision-based Traffic Surveillance Systems
Qian Qing-quan · 2005
In this paper,an object-of-interest based video transmission approach is presented for vision-based traffic surveillance systems using the background subtraction with one reference image.This background is pre-stored at both the image-capturing side and the monitoring center;at the acquisition side,using the badcgroand sabtraction with only one reference image the target objects are extracted,deriving a minimum rectangular grid-based region and a mask matrix for each of the extracted object.The monitoring center,after receiving the necessary codes,can reconstruct the video frames by fusing the objects or their wavelet-transformed versions into the preset background.The advantages are:(1) the networking resources are greatly saved;(2) some high-level processing functionality like collision avoidance,fault alarming can be improved;(3) operators' attention can focus on important events;(4) new services can be added or developed.Experimental results have proved its effectiveness.
