A novel image-based approach for detecting pedestrian crossings to enhance the safety and mobility of blind people while crossing a road is described. This is achieved through bipolarity-based segmentation and projective invariantbased recognition. A thorough evaluation of the proposed approach was conducted using 100 real images with and without crossings. It was found that the proposed techni...

In this paper I explore, via a quantitative spatial macroeconomic model, the contribution of aggl...
