The capability of recognizing pedestrian attributes, such as gender and clothing style, at far distance, is of practical interest in far-view surveillance scenarios where face and body close-shots are hardly available. We make two contributions in this ...

This paper addresses biometric identification using large databases, in particular, iris databases. In such applications, it is critical to have low response time, while maintaining an acceptable recognition rate. Thus, the trade-off between speed and ...

Two large facial-expression databases depicting challenging real-world conditions were constructed using a semi-automatic approach via a recommender system based on subtitles.

Retrieving images to match with a hand-drawn sketch query is a highly desired feature, especially with the popularity of devices with touch screens. Although query-by-sketch has been extensively studied since 1990s, it is still very challenging to build ...

In character recognition, multiple prototype classifiers, where multiple patterns are prepared as representative patterns of each class, have often been employed to improve recognition accuracy. Our question is how we can improve the recognition ...

Monitoring online transactions or tracking users' behavior will generate large-scale archived streaming data in scientific experiments, inner-network audit logs and so on. These archived systems may scale up to petabytes (1015Bytes). Storing and ...

Image retrieval in large-scale databases is currently based on a textual chains matching procedure. However, this approach requires an accurate annotation of images, which is not the case on the Web. To tackle this issue, we propose a reformulation ...

In this paper, a methodology of developing a multimodal interaction system using a large-scale database as a knowledge source is proposed. We extend one application of Rails frameworks, which is used for rapid prototyping of GUI-based Web applications, ...

In a cellular phone system, mobility databases called visitor location registers (VLRs) are used to temporarily hold the subscription information of the roaming users who visit the service area of the VLR. When the users leave the VLR area, the ...
