文档介绍：Long-distance supervisory system data terminal research Based on GPRS
Abstract:Adaptability is one of the key issues in the important area of surveillance systems. Based on attention and sensor samples, the experiential sampling technique provides a general framework for analyzing video data .In this paper , we present a scheme for adaptive monitoring of surveillance objects by utilizing the feed back of the experiential sampling based video surveillance results to change the video camera parameters. Our framework first detects the moving objects in the surveillance video. We then analyze the output of this step to determine the state of the video camera settings. The relevant parameters of the video camera are continuously adjusted based on a proportional feedback control system. The fixed camera is thus adaptively tuned so as to obtain a good quality surveillance video output. We centrally frame the target object by doing panning and zooming operations. Moreover, we utilize the experiential sampling approach to capture the moving objects by utilizing the context which is a function of the current state of the environment as well as past experiences. This adds tremendous flexibility to the surveillance process which can be applied in a wide variety of monitoring situations.
