Feature detection & parallel processing

Question 1

Feature detection

Answer 1

When looking at an object, break it down into its features components to get a sense of what your looking at

Question 2

What are some feature components you have to know for objects?

Answer 2

Color, form (shape), motion

Question 3

Color will come from ______ in our retina

Answer 3

Cones (red, blue, green cones)

Question 4

Trichromatic theory of color vision

Answer 4

Red cones are senstivie to red light & when any color red, blue or gree, hits the same color cone, it will fire an action potential & tell ur brain your looking at that color (red, blue, green)

Question 5

Parvo pathway is used to figure out the _________ of an object, its good at the spatial resolution (also allows us to see in color a bit too)

Answer 5

Form (shape)

Question 6

The parvo lacks ____________ resolution so its only useful for objects staying still

Answer 6

temporal

Question 7

The_____________ is used to allow us to encode(see) motion so it has high temporal resolution (has poor spatial resolution so can’t use it for objects staying still & it doesn’t encode color)

Answer 7

magno pathway

Question 8

Parallel processing

Answer 8

The ability to encode color, form, & motion all the same time when looking at an object
