Virtual image: keyframe or visual icon?

Multimedia technology has been applied to many kinds of applications and the amount of multimedia data is growing dramatically. Especially the usage of digital video data is very popular today. Thus, content-based indexing and retrieval in video is getting more important in the future. In this paper, we propose a new approach for indexing video based on the content of the keyframe. Firstly we explain how this approach is flexible at future improvements in comparison with other methods, and then we propose our keyframe indexing method, based on spatial relationships in the keyframe. For this aim, we will use the virtual image.
