Palmer\u003c\/b\u003e (Author)\u003c\/p\u003e\u003cp\u003eIdentifying and understanding the visual cues that determine relative depth across image contours (i.e., figure-ground organization) are central problems of vision science. 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\n            \u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 84\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.17 x 9 x 6 IN\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e June 25, 2008\u003c\/div\u003e\n            ","brand":"BooksCloud","offers":[{"title":"Default Title","offer_id":53275774845235,"sku":"9783836484060","price":83.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/5595\/6612\/files\/5WemZXBbJC9783836484060.webp?v=1776901198","url":"https:\/\/www.vysn.com\/en-ca\/products\/the-role-played-by-extremal-edges-in-figure-ground-organization-paperback","provider":"VYSN","version":"1.0","type":"link"}
