- 1where are luminance edges and texture edges processedv1
- 2where are disparity defined contours processedv4
- 3where are objects processedLOC
- 4where are parts of objects processedposterior LOC (back)
- 5where are whole objects and object recognition processedanterior LOC (front)
- 6what is the classical bottom up view of visionprocessing starts w stim on retina and works via increasingly complex stages in ever higher brain areas towards some behaviour goal;
- 7what is the what is the classical bottom up view in terms of objectsfirst segment them from background, then identify contours, build contours into object outlines, recognise objects
- 8process by which we separate objects from the backgroundsfigure-ground segmentation
- 9in figure-ground segmentation, which part of the brain finds object edgesretinal ganglion cells / LGN
- 10in figure-ground segmentation, which part of the brain does texture segmentationorientation contrast cells
- 11in figure-ground segmentation, which part of the brain finds motionmotion contrast cell
- 12in figure-ground segmentation, which part of the brain finds direct object segmentationdisparity neurons
- 13illusory contours isperceiving a contour where no line exists
- 14when do illusory contours develop8 months for static
2-3 for moving - 15what part of the brain processes illusory contoursv2
- 16contour integration isthe ability to link up short sections of a contour to form a longer contour
- 17how does contour integration occurlong range excitatory connections between cells that prefer similar orientations but at diff positions
- 18where does contour integration occurv1
- 19where is form processedv4
- 20what do the v4 neurons respond to for formmore complex features than earlier areas but less complex than whole objects
- 21where does the top down influence come inv4. attention. form
- 22what was biedermans theoryrecognition by components
- 23what is biedermans recognition by components theoryearly visual processing; extract edges. cluster edges into groups. separate groups at local concavities (like joints)
- 24what are the rules for clustering edgesbased on features that dont vary w viewpoint, points on curves, parallel points, edges terminate at common point, symmetry, co-linearity, non-accidental features of the world
- 25what do clustered edges form and how many different of these are theygeons. (geometric atoms)
36 diff - 26what does shape recognitionLOC
- 27alternative top down view of objects from computer scientists?a lot easier to find boundaries of object if you already know what it is so recognition precedes segmentation (e.g. quick categories)... higher areas guess what objects are, to lower areas to segment and refine location so higher get more info (v4)
- 28what does the table top illusion highlight to uswe do not see whats in the retinal image
- 29all types of contour come together inv4
- 30what does v4 do overalldetects objects parts like corners
- 31what does LOC do overallprocesses whole objects but is a large complex misunderstood region. probs does object identification
- 32what is size constancyknowing that things stay the same size despite being at diff distances from you
