A new method was proposed for improving the performance in detecting passing persons with high accuracy and high stability in the background subtraction algorithm.  The method, Improved Background Quick Updater (IBQU), was structured by combining with an inter-frame subtraction method and a mode image method.  The excellent performance of the proposed method was achieved by changing the background according to state of the passing person detection.  Additional feedback loop with a switch dramatically improved the performance in detecting a stopping person.  The proposed method was successfully applied to detect a person walking, stopping halfway and walking again.
