Abstract

This paper presents a novel user interaction concept for document image scanning with mobile phones. A high res- olution mosaic image is constructed in two main stages. Firstly, online camera motion estimation is applied to the phone to assist the user to capture small image patches of the document page. Automatic image stitching process with the help of estimated device motion is carried out to recon- struct the full view of the document. Experiments on doc- ument images captured and processed with mosaicing soft- ware clearly show the feasibility of the approach.
