Exam Questions and Verified Answers |
Already Graded A+
bottom-up processing - 🧠 ANSWER ✔✔process where physical stimuli
influence how they perceive them
top-down processing - 🧠 ANSWER ✔✔process where our existing
knowledge of objects influences how they perceive them
recognition - 🧠 ANSWER ✔✔ability to match a presented item with an item
and memory
representation - 🧠 ANSWER ✔✔the storage/reconstruction of information
when it is not in use
perceptual organization - 🧠 ANSWER ✔✔allows you to recognize/organize
objects
,(i.e. grouping, segregation)
grouping - 🧠 ANSWER ✔✔organizing into groups (i.e. chairs, lights, plates,
etc.)
segregation - 🧠 ANSWER ✔✔making sense of different surfaces in a scene
(what is behind, what is in front, etc.)
gestalt psychology - 🧠 ANSWER ✔✔whole is greater than sum of its parts
structuralism - 🧠 ANSWER ✔✔whole = sum of parts
figure-ground organization - 🧠 ANSWER ✔✔distinguishing background vs
foreground of a scene (top vs bottom, background vs foreground)
figure-ground organization rules - 🧠 ANSWER ✔✔symmetry,
convexity/concavity
gestalt laws - 🧠 ANSWER ✔✔good continuation, proximity, similarity,
common region, connectedness, common fate
receptors used for edge detection - 🧠 ANSWER ✔✔V1 detectors
role of angles and edges - 🧠 ANSWER ✔✔carry meaning
- "Y'-shaped edge means a corner
, - "T"-shaped edge means an occlusion
- angles show good continuation
geon - 🧠 ANSWER ✔✔basic component of an object
recognition by components thoery - 🧠 ANSWER ✔✔(Biederman) objects
are recognized by the relation of its geons
viewpoint invariance - 🧠 ANSWER ✔✔recognition of an object is
independent of one's viewpoint
problems wit recognition by components - 🧠 ANSWER ✔✔- viewpoint
invariance is not foolproof (preferred viewpoint leads to faster recognition)
- many geon combinations can be perceived as multiple things
- faces/letter recognition
template theory - 🧠 ANSWER ✔✔recognition is a point-by-point comparison
to a stored "average or ideal" representation
problems with template theory - 🧠 ANSWER ✔✔- multiple stored
representations with all possible variations (requires lots of memory space!)
- separate representations needed for all viewpoints
