| Abstract(in English) | We propose a novel method using a tree-structured codebook and a node selection technique for high-level feature extraction from video data. We first quantize local SIFT descriptors to construct a tree-structred codebook shared among all the high-level features. Then, we select nodes to be used as visual words for each high-level feature. We also propose motion words which are defined as visual words with motion activities. We evaluate the proposed method using TRECVID 2006 and 2007 database. By selecting nodes, Mean Average Precision(MAP) improved from 0.097 (baseline) to 0.100. By using the motion word, MAP father improved to 0.102. These results confirmed the effectiveness of the proposed method. |
