Slide1:  Perception of Depth Slide2:  The Retinal Image is 2-D, but what information is available to construct the 3-D environment? 1. Oculomotor Cues Slide3:  1. Oculomotor Cues b) Accomodation Slide4:  2. Pictorial Cues a) Occlusion (overlap) b) Size in the field of view c) height in the field of view Slide5:  2. Pictorial Cues linear perspective texture gradient Slide6:  2. Pictorial Cues texture gradient Slide7:  2. Pictorial Cues atmospheric perspective Slide8:  shading 2. Pictorial Cues Slide9:  3. Motion Cues a) Motion parallax - when an observer moves, objects nearer the observer move faster than more distant objects A B T A H A T B H B Slide10:  Motion Parallax Slide11:  3. Motion Cues b) Deletion/Accretion Slide12:  3. Motion Cues b) Deletion/Accretion Slide13:  4. Binocular Disparity for Stereopsis Slide14:  4. Binocular Disparity for Stereopsis -stereoscope (ViewMaster) -3-D movies in the 50s with red green glasses -Magic Eye fixate blue object -image falls on corresponding points in the retinae horopter - all images fall on corresponding points on the retina Slide15:  4. Binocular Disparity for Stereopsis angle of disparity images of objects not on the horopter do fall on non-corresponding points on the retina Slide16:  4. Binocular Disparity for Stereopsis the further away from the horopter, the greater the angle of disparity Slide17:  4. Binocular Disparity for Stereopsis things in front of the horopter are in crossed disparity things behind the horopter are in uncrossed disparity Slide18:  4. Binocular Disparity for Stereopsis Retinal disparity is sufficient to create the perception of depth Bela Julesz - Random dot stereograms must solve the correspondence problem Slide19:  Figure 7.24, page 240 Random dot stereogram Copyright © 2002 Wadsworth Group. Wadsworth is an imprint of the Wadsworth Group, a division of Thomson Learning Slide20:  4. Binocular Disparity for Stereopsis autostereograms (Magic Eye) -disparity in a single image Slide21:  Figure 7.25, page 241 Disparity selective cell Copyright © 2002 Wadsworth Group. Wadsworth is an imprint of the Wadsworth Group, a division of Thomson Learning Binocular Neurons in Visual Cortex are disparity specific Slide23:  Binocular Neurons in Visual Cortex are disparity specific Visual Cortex LGN zero disparity “far” “near” -cats monocularly deprived for the first few months of life lack binocular cortical neurons and stereopsis Slide26:  Perceived Depth and Size of objects MUST Be codependent -if perceived at the same distance, then they must be the same size -if one is perceived as larger, then it must be further away than the other Slide27:  Size Constancy: We perceive an object's physical size irrespective of it's distance from us A <A We can do this because of depth information - size-distance scaling mechanism Slide28:  Holway and Boring (1941) Subjects always matched the physical size of the test circle Subjects matched visual angle when cues were removed Slide29:  Emmert's Law - the farther away an afterimage appears, the larger its size Slide31:  Emmert's Law - the farther away an afterimage appears, the larger its size S p (S r D p = K ) X Slide32:  Muller-Lyer Illusion Slide33:  Muller-Lyer Illusion Slide34:  Muller-Lyer Illusion conflicting cues theory Slide35:  Muller-Lyer Illusion Slide36:  Perceptual Illusions Which monster appears larger? The Ponzo Illusion Slide37:  Perceptual Illusions The Ponzo Illusion Slide38:  Ames Room Ames Room:  Ames Room The Ames room is designed so that the monocular depth cues give the illusion that the two people are equally far away Slide40:  Page 151 (258, Fig. 7.51) The Ames Room Copyright © 2002 Wadsworth Group. Wadsworth is an imprint of the Wadsworth Group, a division of Thomson Learning Slide41:  Moon Illusion Slide44:  assimilation theory (angular-size contrast theory) -moon appears smaller when surrounded by larger objects
