This paper presents a novel video mosaicing method capable of generating a geometric distortion-free mosaic image using a hand-held camera. For a document composed of curved pages, mosaic images of virtually flattened pages are generated. The process of our method is composed of two stages : real-time stage and off-line stage. In the real-time stage, image features are automatically tracked on the input images, and the viewpoint of each image as well as the 3-D position of each image feature are estimated by a structure-from-motion technique. In the off-line stage, the estimated viewpoint and 3-D position of each feature are refined and utilized to generate a geometric distortion-free mosaic image. We demonstrate our prototype system on curved documents to show the feasibility of our approach.
