Exam 2 Review Flashcards
Hue
the color’s name
Saturation
The intensity of the color
Brightness
how light or dark a color is
what is a color?
perceived color is a property of how light is reflected off an object given its material
Why is purple special?
there is no wavelength for purple
why are you color blind at night
only the rods are sensitive enough to pick up the light in dim areas
Opponency
caused by interconnected cells in the retina (bipolar, amicrine, and horizontal)
Color constancy
the color you see in the combo of the reflectance of an object and the light source
a change in electromagnetic variation leads to
a change in color
trichromacity
having three cones
Monocular depth cues
depth cues that can be seen with one eye
two types of monocular depth cues
static and dynamic
types of static depth cues
position based, size based, lighting based
dynamic cues
motion parallax, optic flow, deletion and accretion
static depth cues: Patial Occlusion
when something is partially covered up and it infers depth. ex: a car in front of a light post is closer to you
static depth cues: relative height
things at the top of an image are closer to you
static depth cues: linear perspecitve
like railroad tracks
static depth cues: familiar size
compare to past knowledge to something else in the world
static depth cues: texture gradient
more detailed is closer
static depth cues: relative size
compare to other objects in the picture
static depth cues: atmospheric perspsecive
cloudy when farther away. think mountains
static depth cues: shading
a face has shading. the eye is not black it is just set into the skull
static depth cues: cast shadows
shadows infer light source
binocular disparity
the difference in image locations between the left and right eye that informs depth informaiton
