Most of the methods for video summarization relay on complicated clustering algorithms that makes them too computationaly complex for real time applications. In this paper we propose an efficient approach for video summary generation that does not relay on complex clustering algorithms and does not require frame length as a parameter. Our method combines MPEG-7 Color Layout Descriptors with adaptive threshold technique to detect shot boundaries. For each shot a keyframe is extracted and similar keyframes are eliminated in a simple manner. A MOS measure evaluation on a standard dataset show that the method produces video summaries of highest visual quality.

W artykule zaproponowano nieskomplikowany algorytm do tworzenia skrótów materiałów wideo. Metoda łączy w sobie deskryptor warstwy koloru MPEG-7 z techniką progu adaptacyjnego, co pozwala na wykrywanie granic stopklatki. Dla wielu takich samych lub podobnych klatek, pozostawiana jest tylko jedna z nich.
