Marker-assisted recognition of dynamic content in public spaces

Abstract

In this work we present an image processing-based assistant for helping visually impaired citizens with the task of recognizing dynamic content within fixed layouts of displays in public spaces. Our solution relies on the placement of markers, in order to facilitate the location and recognition of target objects and, at the same time, provide hints to users about how to better position their mobile device's cameras to capture the whole information contained in the display.
