<P>PROBLEM TO BE SOLVED: To provide a human detection method that can image an object approaching a terminal with a digital video camera and accurately detect and store information such as a user's face from the input video. <P>SOLUTION: The human detection method includes: a step of initializing parameters used for human detection; a step of determining whether a current mode is a face detection mode; a step of performing face detection on each input video frame if the current mode is the face detection mode, and when a face is not detected even after a predetermined number of face detection trials, selecting a motion detection mode and going back to the second step; and a step of performing motion detection on a predetermined number of video frames input in a unit if the current mode is the motion detection mode, and when at least a predetermined number of motion detection cycles are performed successfully within a predetermined period of time, going back to the first step. The face detection mode and the motion detection mode are repeatedly or complementarily performed while a monitoring system is operated, so that accurate human detection, high speed execution, and high video storage efficiency can be achieved. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
