INCREMENTAL CONSTRUCTION OF SEARCH TREE WITH SIGNATURE POINTERS FOR IDENTIFICATION OF MULTIMEDIA CONTENT
摘要
Search tree structures with nodes that represent signatures derived from segments of video and audio content are used by systems to identify content and re-establish the correct alignment between video and audio content that have become disassociated with one another. The amount of storage needed to record data representing the tree structure can be reduced by replacing stored signature sets with signature pointers. The efficiency of searches in the tree structure can be improved by constructing and using partial tree structures.
