A New Method for Motion Target Detection by Background Subtraction and Update

In this paper, a new method for motion target detection by background subtraction and update is proposed in order to modify the deficiencies of the traditional detection methods. In this scheme, the dynamic threshold can make up for the shortcomings of misjudge by fixed threshold background subtraction so as to extract most motion pixels. The local background updating strategy based on double threshold counting can promptly update background and overcome the shortcomings of the traditional background updating methods. The morphological processing method is applied to remove various noises to polish the image edge. The experimental results show that the proposed method has the low computational complexity, and can well detect the motion target under the very complex background. (C) 2012 Published by Elsevier B.
