Abstract

Digitalized terrestrial broadcast can offer many programs to the TV viewer like communication satellite broadcasting. And it will spread in Japan. And image retrieval is necessary for us to watch many programs. Thereupon, we proposed method that particular scene is retrieved from video image. That retrieval method is to use the motion vector contained in MPEG-2 stream. Concretely, the movement of image is defined as the characteristics from information of motion vector. And the characteristic of a retrieval object and retrieval query scene are compared. In this way, target scene is retrieved. And we examined about efficacy of this retrieval method by using a television image.
