Abstract
Content-based video retrieval, CBVR, is an active research topic. To make this feasible, development of a query language, which is simple (i.e., intuitive), yet powerful, is essential. In this paper, we propose a mosaic-based visual language for CBVR. Mosaicing is a well-known technique in computer vision and graphics for creating a comprehensive overview of a scene reproduced in a set of images. The language supports the specification of queries encompassing motion of objects and camera, as well as visual features, by arranging visual components on a mosaic image. The proposed language has then used to implement a graphical interface that allows users to specify and refine queries to a video database.
