While reading devices for the visually impaired have been available for many years, they are often expensive and difficult to use. The image processing required to enable the reading task is a composition of several important sub-tasks, such as image capture, image stabilization, image enhancement and page-curl dewarping region segmentation, regions grouping, and word recognition In this paper we deal with some of these sub-tasks in an effort to prototype a device (Tyflos-reader) that will read a document for a person with a visual impairment and respond to voice commands for control. Initial experimental results on a set of textbook and newspaper pages are also presented.
