In this monograph we report the figural cue of extremal edges (EEs), which arise when an opaque con-vex surface smoothly curves to occlude part of itself. We also compare classical cues to figure-ground organization with the recently disco-vered cue of EE. Our results show that EEs are surprisingly powerful pictorial cues to relative depth across a contour, almost entirely dominating the well-known figure-ground cues of relative size, con-vexity, surroundedness, and shape familiarity. These results demon-strate that natural shading and texture gradients in an image provide important additional information about figure-ground organization that has been overlooked in the past 75 years in research on figure-ground organization.\u003c\/p\u003e","brand":"VDM Verlag Dr. Mueller E.K.","offers":[{"title":"Paperback","offer_id":47586874359959,"sku":"9783836484060","price":4511.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9783836484060.webp?v=1774965567","url":"https:\/\/atlanticbooks.com\/products\/the-role-played-by-extremal-edges-in-figure-ground-organization-9783836484060","provider":"Atlantic Books","version":"1.0","type":"link"}
