In this paper, we propose a new image annotation method by combining content-based image annotation and tag-based image annotation techniques. Content-based image annotation technique is adopted to extract "loosely defined concepts" by analyzing pre-given images' features such as color moment (CM), edge orientation histogram (EOH), and local binary pattern (LBP), followed by constructing...
In this paper, we study the performance of global features and local features for the semantic concept detection problem, which is a crucial task for video indexing and retrieval applications. We have performed a comprehensive evaluation of these features on TRECVID datasets that are used in the concept detection benchmark from 2005 to 2009. The experimental results show that with appropriate choice...
