Web databases contain a huge amount of structured data which are easily obtained via their query interfaces only. The query results are presented in dynamically generated web pages, usually in the form of data records, for human use. The automatical web data extraction is critical in web integration. A number of approaches have been proposed. The early work are most based on the source code or the...
The rapid increase of digital video data makes video query increasingly important. To better satisfy users' video query requirements, developing a user-friendly functional video query interface has become an interesting task. In this paper, we design and implement a visual query interface for video databases. In the interface, we combine the advantages of graph and text, making the interface not only...
Bag of words (BoW) model, which was originally used for document processing field, has been introduced to computer vision field recently and used in object recognition successfully. However, in face recognition, the order less collection of local patches in BoW model cannot provide strong distinctive information since the objects (face images) belong to the same category. A new framework for extracting...
As a crucial security problem, anti-spoofing in biomet-rics, and particularly for the face modality, has achieved great progress in the recent years. Still, new threats arrive in form of better, more realistic and more sophisticated spoofing attacks. The objective of the 2nd Competition on Counter Measures to 2D Face Spoofing Attacks is to challenge researchers to create counter measures effectively...
While extracting feature vectors to represent image content remains an important issue especially those semantic features, how to measure the similarity of these feature vectors and maximize their relevance to visual content becomes an attractive research topic over the recent years. Following this trend, we proposed a new similarity measurement by introducing a correlation test into the conventional...
