A Survey on Video Caption Extraction

Over the last few decades, Content-based image/video retrieval (CBIR/CBVR) problem have developed a new height. As one of the most impartment methods of CBVR, video caption extraction obtained more and more application. A large number of techniques have been proposed to address this problem, we summarized most of the video caption extraction methods, analyzed the advantage and disadvantage of the existed methods. The purpose of this paper is to classify and review these algorithms, discuss benchmark data and performance evaluation, and to point out promising directions for future research.
