Abstract
There are many videos about sports. In sports videos, the motions carry much information about shots. This paper proposes the video retrieval system based on the motions. We have many criteria about sameness. The method retrieves videos based on the similarity of the all motions described in frames. The method gets the motions using the reliable motion estimation method, and make the 1-dimensional projections from the X motion, Y motion and the reliabilities. Resulting image has the 1-dimensional space axis and the 1-dimensional time axis. Using the images, the method retrieves shots as fast as the image retrievals do. This paper proposed the video retrieval method and shows the experiments about baseball games.
