spatial vision

Question 1

spatial vision

Answer 1

variations in luminance ACROSS SPACE

Question 2

spatial resolution

Answer 2

highly sensitive measure of visual funtion - visual acuity and contrast sensitivity

Question 3

peak of sine wave grating

Answer 3

bright/light bar

Question 4

trough of sine wave grating

Answer 4

dark bar

Question 5

sine wave grating

Answer 5

alternating bright and dark bars with a gradual transition

Question 6

frequency

Answer 6

more waves/waves closer together = high. opposite low.

Question 7

gain

Answer 7

image contrast/object contrast

Question 8

MTF

Answer 8

modulation transfer function - rations for fundamental set of inputs

Question 9

fundamental set

Answer 9

simple input signals that is used to build complex stimuli

Question 10

perfect optical system MTF value

Answer 10

1

Question 11

perfect optical system MTF value

Answer 11

1

Question 12

optical blur

Answer 12

high frequency loss

Question 13

suprathreshold

Answer 13

adaptation to the higher frequency desensitized the higher spatial frequency channels -

Question 14

adaptation experiment

Answer 14

adaptation to the higher frequency desensitized the higher spatial frequency channels -

Question 15

isotropy

Answer 15

sampling characteristics same in all ORIENTATIONS about the visual axis - better for horizontal and vertical gratings

Question 16

homogeneity

Answer 16

sampling characteristics are the same in all POSITIONS across visual fields - deals with just the FOVEA
