Paper Abstract

In this paper the method is presented to retrieve based on image content in video database using DC-image. The DC-image with the DC coefficient is extracted from DCT domain of image in this video database model. The principle of DC-image and three different extraction methods of the DC-image from MPEG video stream are described. With the DC-image, temporary segmentation of compress video is realized depending the histogram of DC-image. Comparing the performance of three extracting methods and analyzing the result of DC-image extracted by different methods, we propose a video database structure and feature extraction method. To create the uniform indexing for video clip, the expression format of frame is developed by normalized histogram of DC-image.
