| Research Abstract |
Video telop retrieval systems based on telop characters can retrieve the corresponding telops to the query from the huge video data. On this research, a new telop retrieval system based on telop characters is developed. In order to specify the suitable telop, this method calculates the distance between each image features of telop characters and template image features of query keyword. Experimental results, using 91 query keywords, show that the average precision of proposed method using 1-gram feature becomes 98. 61%, and using 2-gram feature becomes 99. 59%. Moreover, the retrieval time can be obtained in about 0. 5 seconds when using 2-gram feature
