    "title": "Effects of Object Structure on Recognizing Novel Views of Three-Dimensional Objects",
    "subtitle": null,
    "abstract": "Can observers recognize novel views of\nthree-dimensional (3-D) objects, created by rotations\nin depth from a single familiar view? Three\nexperiments using 3-D model objects are reported\ndemonstrating that: (a) subjects can indeed recognize\nnovel views under these circumstances, and (b)\nrecognition accuracy depends on the types of objects\nemployed. More precisely, subjects successfully\nrecognized geometricallyregular and irregular objects\nrotated by 180 degrees about the vertical ^ ) axis.\nHowever, only geometricallyregular objects w o e\nrecognized w h e n rotated similarly by 9 0 degrees.\nThesefindingscannot be easily\naccommodated by contemporary object-centered or\nviewer-centered theories of shape-based object\nrecognition, which m a k e no provisions for\nrqnesenting different types of objects uniquely.\nAlternatively, thesefindings support a theory in\nwhich inferences about objects' 3-D shapes are\ngenerated from information implicit in their two-\ndimensional (2-D) bounding contours, or silhouettes\n(Johnson, 1993). Such inferences m a y be premised\non rules that C2q)ture importantregularities between 2-\nD bounding contours and 3-D surface geometry (e.g.,\nBeusmans, Hofiman, & Bennett, 1987; Richards,\nKoenderink, & Hoffinan. 1987).",
