Description: Here in our demos, you will see several examples of the fascinating contour erasure effect: objects completely disappear into the background or merge together after only a short adaptation period on their contours. Contour erasure, first discovered by Stuart Anstis in 2013, describes the phenomenon that low-contrast objects could completely disappear or be filled in by the background texture after being adapted to flickering contour outlines that match the objects edges. Such contour adaptation drastically speeds up the filling-in process, leading to an instantaneous filling-in percept. Such contour erasure effect reveals the importance of edge information in perceiving objects and surfaces as well as the mechanism underlying perceptual filling-in. Contact me: yih-shiuan.lin@ur.de
