Abstract—The paper proposes a moving-object detection algorithm. An auxiliary object is designed and worn on the user’s brow. The user can issue commands by moving the object vertically or horizontally or opening its mouth. By segmenting the moving-object and analyzing the variation of center of gravity of the segmented object, or by segmenting user’s mouth and analyzing the variation of the segmented mouth area, the algorithm can recognize up, down, left, right, and enter commands issued by the user. The software simulation results are given to demonstrate the effectiveness of the proposed algorithm. The algorithm can benefit the video input device.
Index Terms—Center of gravity, moving-object detection, segmentation, video input device.
