Near Their Thresholds for Detection, Shapes Are Discriminated by the Angular Separation of Their Corners

Dickinson, J. Edwin; Bell, Jason; Badcock, David Russell


Observers make sense of scenes by parsing images on the retina into meaningful objects. This ability is retained for line drawings, demonstrating that critical information is concentrated at object boundaries. Information theoretic studies argue for further concentration at points of maximum curvature, or corners, on such boundaries [1]-[3] suggesting that the relative positions of such corners might be important in defining shape. In this study we use patterns subtly deformed from circular, by...[Show more]
