SCENE SWITCHING DETECTION SYSTEM, SCENE SWITCHING DETECTION PROGRAM, AND SCENE SWITCHING DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a scene switching detection system suitable for detecting the switching of a scene according to the desire of a user.;SOLUTION: A moving image of a moving image registration DB10 is divided into frame units so that a plurality of static images can be prepared, an area under consideration is extracted from each of the static images, and the feature vector of each of the static images is generated on the basis of the extracted area under consideration. Then, the leading static image on a reproduction time axis among the plurality of static images continuing on a reproduction time axis is used as a reference static image, and each static image other than the reference static image among the plurality of static images is used as a comparison static image. The inter-vector distance between the feature vector of the comparison static image and the feature vector of the reference static image is calculated for each comparison static image. When the calculated inter-vector distance is equal to or greater than a predetermined value, the reproduction point of time of the comparison static image is detected as the switching point of a scene.;COPYRIGHT: (C)2005,JPO&NCIPI
