Application of MPEG-7 descriptors for temporal video segmentation

Due to the rapidly growing multimedia content available on the internet it is highly desirable to index multimedia data automatically and to provide content based search and retrieval functionalities. The first step in order to describe and annotate video data is to split the sequences into sub-shots which are related to semantic units. This paper addresses unsupervised scene change detection and keyframe selection of video sequences. Unlike other methods this is performed by using a standardized multimedia content description of the video data. We apply the MPEG-7 scalable color descriptor and the edge histogram descriptor [1] for shot boundary detection and show that this method performs well. Furthermore, we propose to store the output data of our system in a video segment description scheme to provide simple but efficient search and retrieval functionalities for video scenes based on color features.
