| Abstract(in English) | A lot of home videos have been taken very easily and therefore stored disorderly these days. It is a forthcoming problem to manage and retrieve those videos easily. This paper proposes a method to segment and label sub-shots of home videos based on the discrimination of camerawork and moving objects. The method uses the assumption that people tend to arrange a focusing object around the center of the video frame when taking a video. Following the assumption, the method divides the video frame into an internal and an external area beforehand, and calculates the feature parameters based on the motion vector of feature points at each area. Each video frame is classified into six categories by the feature parameters using the distance from studied parameters. Experiments found that video frames can be classified more appropriately than the method without frame dividing, and shows the possibility to handle videos with hand swinging and unstable camerawork properly by this method. |
