chapter 4 Flashcards
extrastriate cortex
the regions that border v1, progressively tuned for more complex features
depth
when one object is in front of another, there will be a visual border formed between the object and the background
gestalt
pattern or configuration
gestalt psychology
wertheimer, kohler, kofka
illusory contour
a false edge that is perceived but is not present in the physical stimulus
occlusion
when an object is covered up by another object
good continuation
two elements will tend to group together if they seem to fall on the same line
closure
a closed contour is preferred to an open contour
texture segmentation
parsing an image into regions of common texture properties
similarity
features group together if similar in size/shape/etc
proximity
features group together if they are close to each other
parallelism
parallel contours tend to group together
symmetry
symmetrical regions are more likely to be grouped
figure-ground segmentation
the process of determining which item belongs to the foreground and which item belongs in the background
global superiority effect
many experiments suggest that the properties of the whole object dominate local identities
