![]() ![]() Having determined single shot positions as well as the visual highlights, the information is jointly stored with meta-textual information in an MPEG-7 description scheme. Further, we extract the temporal positions of single obstacles on the course by analyzing MPEG-7 edge information. ![]() We especially concentrate on MPEG-7 based feature extraction and content description, where we apply different visual descriptors for cut detection. We review recent approaches to content- based indexing and annotation of videos for different kind of sports and describe our approach to automatic annotation of equestrian sports videos. Since manual video annotation can be time consuming, automatic annotation systems are required. The huge amount of multimedia data produced worldwide requires annotation in order to enable universal content access and to provide content- based search-and-retrieval functionalities. Hoeynck, Michael Auweiler, Thorsten Wellhausen, Jens MPEG-7 based video annotation and browsing On the test set, the quantization parameters in MPEG-2 I-frames are estimated with an overall accuracy of 99.9% and the PSNR is estimated with an overall average error of 0.3dB. An adaptive deringing method using texture classification is presented. The results of this analysis is used for deblocking and deringing artifact reduction and no-reference PSNR estimation without. A method to estimate the quantization parameters of DCT coded images and MPEG I-frames at the macro-block level is presented. Solutions are presented for MPEG-2 video. The goal is to assess MPEG video quality and perform post-processing without access to neither the original stream nor the code. ![]() We propose no-reference analysis and processing of DCT (Discrete Cosine Transform) coded images based on estimation of selected MPEG parameters from the decoded video.
