27 Aug 1999TL;DR: In this paper, a histogram recognition operation is used to identify a motion of an object in a motion region image of the object. But the method is not suitable for the detection of human motion.
Abstract: A system and method obtain images of an object and generate a motion region image of the object. The motion region image is processed to obtain normal gradients of the portion of the object that has been moved. The normal gradient data is further processed to remove erroneous data points. The erroneous data can be removed by using either an eroding method or a threshold method. After the erroneous data is removed, the remaining gradient information is used to identify a motion of the object. This can be performed using a histogram recognition operation.
