Summary

VideoQ expands the traditional search methods (e.g., keywords and subject navigation) with a novel search technique that allows users to search video objects based on a rich set of visual features and spatio-temporal relationships. Our objective is to investigate the full potential of visual cues in object-oriented content-based video search. Some of the unique features of VideoQ include:

• Automatic arbitray-shape video object segmentation and tracking.
• A rich visual feature library including color, texture, shape, and motion.
• Multi-object spatio-temporal video query (absolute and relative locations).

VideoQ currently supports a large database of digital videos. Individual videos are automatically segmented into separate shots. Currently, over 2000 shots are stored. Each shot is compressed and stored in three layers to meet different bandwidth requirements.

In addition to query by sketch, the user can browse the video shots or search video by text. The video shots are cataloged into a subject taxonomy, which the user can easily navigate. Each video shot has also been manually annotated so the user can perform simple text search of keywords.
