Scalable Indexing of HD Video
Résumé
Video Indexing technique is crucial in multimedia applications. In the case of HD (High Definition) Video, the principle of scalability is of great importance. The wavelet decomposition used in the MJPEG2000 provides this property. In this paper, two descriptors for indexing of HD Video are presented. The first one is based on the GM (Global Motion) of the Video and the correlation matrix is used as similarity measure for matching. The second one is object-oriented and uses histograms in the wavelet domain as indexes; similarity measure is then based on histogram intersection. The complete process of extraction of objects of interest and to determine GM are also detailed.
