PPVK Vision 5

Question 1

Binocular vision

Answer 1

referring to two eyes

Question 2

Binocular summation (binokularna sumacija)

Answer 2

combination of signals from both eyes
make performance of many tasks better than with one eye alone

Question 3

Binocular disparity (biokularno nepodudaranje)

Answer 3

differences between the images falling on our two retinas

Question 4

Stereopsis

Answer 4

binocular perception of depth, impression of 3Dality

Question 5

Depth cue

Answer 5

information about the third dimension in visual space

Question 6

Monocular depth cue

Answer 6

depth cue that is available even when the world is viewed with one eye alone

Question 7

Binocular depth cue

Answer 7

depth cue that relies on information from both eyes

Question 8

Occlusion (Okluzija)

Answer 8

znak za redoslijed relativne dubine u kojem, na primjer, jedan objekt djelomično zaklanja pogled na drugi objekt

Question 9

Relative size

Answer 9

comparison of size of items without knowing the absolute size of either one

usporedba veličine predmeta bez poznavanja apsolutne veličine bilo kojeg

Question 10

Texture gradient

Answer 10

a depth cue based on the geometric fact
items of the same size form smaller, closer spaced images the farther away they get

Question 11

Relative height

Answer 11

Objects farther away will be seen as higher in the image

udaljenije objekte vidimo kao da su višlji

Question 12

Familiar size

Answer 12

a cue based on knowledge of familiar size of objects

Question 13

What can give us metrical information?

Answer 13

relative size and relative height

Question 14

Relative depth cue

Answer 14

specifies that boject A is twice as far away as object B

Question 15

Absolute metrical depth cue

Answer 15

dubinski znak koji pruža mjerljive informacije o udaljenosti u trećoj dimenziji

Question 16

Linear perspective

Answer 16

a depth cue based on the fact that lines that are paralllel in 3D world will appear to converge in 2D image

Question 17

Vanishing point

Answer 17

prividna točka u kojoj se spajaju paralelne linije koje se povlače u dubinu

Question 18

Motion parallax

Answer 18

a type of depth perception cue in which objects that are closer, appear to move faster than objects that are far away

Question 19

accomodation

Answer 19

the process by which the eye changes its focus

Question 20

convergence

Answer 20

the ability of the two eyes to move inwar; to focus on nearer objects

Question 21

Corresponding retinal points

Answer 21

These are spots on each eye’s retina that are the same distance from the center (fovea). When both eyes look at the same object, its image lands on these matching spots in each eye

Question 22

Horopter

Answer 22

• multitude of points in visual space that lead to single vision
• objects on horopter are seen as single images when viewed with both eyes

Question 23

Panum’s fusional area

Answer 23

the region of space, in front of and behind the horopter, within which binocular single
vision is possible

Question 24

Diplopia

Answer 24

double vision

Question 25

Crossed disparity

Answer 25

znak nesrazmjera stvoren od strane objekta ispred ravnine horoptera slike ispred horoptera su pomaknut ulijevo u desnom oku, a desno u lijevom oko

Question 26

Uncrossed disparity

Answer 26

the sign of disparity created by objects behind the plane of the horopter images behind the horopter are displaced to the right in the right eye and to the left in the left eye

Question 27

Stereoscope

Answer 27

a device for presenting one ime to one eye, and other image to other eye oculus rift headset (modern example)

Question 28

Free fusion

Answer 28

poor man stereoscope

Question 29

Stereoblindness

Answer 29

inability to make use of binocular disparity as a depth cue, 3-5% of population

Question 30

Random dot stereogram

Answer 30

stereogram made of a large number of randomly placed dots , no monocular cues for depth

Question 31

Correspondence problem (predstavljanje)

Answer 31

Kod binokularnog vida, problem određivanja koji bi dio slike u lijevom oku trebao biti usklađen s kojim bitom u desnom oku.

Question 32

Uniqueness constraint

Answer 32

feature in the world is represented exactly once in each retinal image | značajka u svijetu predstavljena je točno jednom na svakoj slici mrežnic

Question 33

Continuity constraint

Answer 33

except the edges of objects, neighbouring points in the world lie at similair distances from viewer

Question 34

In ________ most neurons can be influenced by input from both _____ and _______ - that is, they are________

Answer 34

V1, left, right, binocular

Question 35

How many receptive fields has binocular neuron?

Answer 35

two, one in each eye

Question 36

Many binocular neurons respond best when the retinal images are on ________ _________ in the two retinas (neural basis for _____)

Answer 36

correspoinding points, horopter

Question 37

many other binocular neurons respond best when similar images occupy ______ _______ _______ on the retinas of the two eyes (tuned to particular _______ _________)

Answer 37

slightly different positions, binocular disparity

Question 38

In which areas occur: motion parallax depth order depth intervals complex 3D shapes

Answer 38

middle temporal area V2 V4 inferotemporal cortex

Question 39

Binocular rivarly

Answer 39

the competition between the two eyes for control of visual perception
