Abstract :
The ability of gaining visual information from the environment can be of utmost importance for visually impaired and blind people. Our experimental system, consisting of a cell phone and a compact cellular visual computer, is able to detect and recognize objects and understand basic events around the user in predefined situations to help them in everyday tasks. We developed algorithms for two important new tasks: pedestrian crosswalk detection and identification of gender pictograms.
