【 摘 要 】

Problem statement: To extract the moving objects, vision-based surveillance systemssubtract the current image from a predefined background image. The efficiency of these systemsmainly depends on accuracy of the extracted background image. It should be able to adapt to thechanges continuously. In addition, especially in real-time applications the time complexity of thisadaptation is a critical matter. Approach: In this study, to extract an adaptive background, acombination of blocking and multi-scale methods is presented. Because of being less sensitive to localmovements, block-based techniques are proper to control the non-stationary objects
