This paper conducts a formal study of the shot boundary detection problem. First, a general formal framework of shot boundary detection techniques is proposed. Three critical techniques, i.e., the representation of visual content, the construction of

Image annotation has been an active research topic in recent years due to its potentially large impact on both image understanding and Web image search. In this paper, we target at solving the automatic image annotation problem in a novel search and

Two open problems remain unsolved in the content based video retrieval area. Firstly, how to find useful information and express it by different features. Secondly, how to fuse the heterogeneous information together to boost the retrieval performance

Extraction and utilization of high-level semantic features are critical for more effective video retrieval. However, the performance of video retrieval hasn't benefited much despite of the advances in high-level feature extraction. To make good use o

In this paper, we propose a unified shot boundary detection framework by extending the previous work of graph partition model with temporal constraints. To detect both the abrupt transitions (CUTs) and gradual transitions (GTs, excluding fade out/in)

Shot boundary detection servers as a preliminary step to structure the content of videos. Up to now, a large number of methods have been proposed. We give a brief overview of previous works with a novel view, focusing on the solutions of the two main

In this paper, we use a generalized model for all the previously proposed pixel-wise authentication schemes. Then we show how this model can be compromised with an Oracle attack. This motivated us to develop a novel authentication scheme to be descri

The Yeung-Mintzer (Y-M) image authentication scheme has been well studied. Several vulnerabilities and modified schemes to fix them have been reported. In this paper, we propose a novel oracle attack on the Y-M scheme and its variations. Our attack i
