Sketch-based Video Browser (or Video Hunter) - (A video retrieval tool for known-item search tasks.)

Sketch-based Video Browser (or Video Hunter) is a new tool focusing on known-item search tasks, where users have seen some video scene, know it is contained in a collection, but do not know where it is located. Therefore, users have to search/browse the collection with advanced techniques enabling query idea initialization, result visualization and browsing. Given such support, known-item search is not restricted just to ideal query formulation. The Video Hunter tool has participated in the Video Browser Showdown, winning the competition in 2014 and 2015.
