Raindrop Complement based on Epipolar Geometry and Spatiotemporal Patches

In this paper, we propose detection and complement of raindrops on mirrors and windows onto cars. Raindrops on windows and mirrors disturb view of drivers. In general, they were removed using wiper and special devices. However, the devices cannot be used for general case. In our proposed method, images of mirrors and windows are taken by camera and raindrops are complemented on the images, virtually. The method is based on auto-epipolar geometry and concept of spatiotemporal image. By using the method, we can observe clear windows and mirrors only if we can take them by camera.
