CamWorks: A Video-based Tool for Efficient Capture from Paper Source Documents
William Newman, Chris Dance, Alex Taylor, Stuart Taylor, Tony Aldhous, Michael Taylor
We describe the design and evaluation of CamWorks, a system that employs a video camera as a means of
supporting capture from paper sources during reading and writing. The user can view a live video image of the
source document alongside the electronic document in preparation. We describe a novel user interface
developed to support selection of text in the video window, and several new techniques for segmentation,
restoration and resolution enhancement of camera images. An evaluation shows substantially faster text
capture than with flatbed scanning.
