U-Cker: Initial Development of an Interactive Video Retrieval System for Novice Users

We present U-Cker, an interactive video retrieval system designed for novice users, developed for the VR4B (Video Retrieval for Beginners) special session at the CBMI conference. The system builds on our previous developments for the TRECVID video retrieval benchmark, where we solely focused on search accuracy and did not consider real-time operation or usability. U-Cker addresses this limitation by enabling real-time interaction while maintaining high retrieval performance. Furthermore, the user interface has been significantly simplified to ensure accessibility for users with no prior experience in video retrieval. The system runs entirely in a web browser, which does not require additional software installation and provides easy access for all users.
