distant mountains.) Painters, notably Cezanne, employ "warm" pigments (red, yellow and orange) to bring features forward towards the viewer, and "cool" ones (blue, violet, and blue-green) to indicate the part of a form that curves away from the picture plane. The color of distant objects is also shifted towards the blue end of the spectrum. Color vision - Correct interpretation of color, and especially lighting cues, allows the beholder to determine the shape of objects, and thus their arrangement in space.When driving, we are constantly judging the dynamically changing headway (TTC) by kinetic depth perception. Using kinetic depth perception enables the brain to calculate time to crash distance (aka time to collision or time to contact - TTC) at a particular velocity. As objects in motion become smaller, they appear to recede into the distance or move farther away objects in motion that appear to be getting larger seem to be coming closer. Depth from motion - One form of depth from motion, kinetic depth perception, is determined by dynamically changing object size.some types of birds, which bob their heads to achieve motion parallax, and squirrels, which move in lines orthogonal to an object of interest to do the same). Some animals that lack binocular vision due to wide placement of the eyes employ parallax more explicitly than humans for depth cueing (e.g. This effect can be seen clearly when driving in a car nearby things pass quickly, while far off objects appear stationary. Motion parallax - When an observer moves, the apparent relative motion of several stationary objects against a background gives hints about their relative distance. ![]() Depth perception combines several types of depth clues grouped into two categories: monocular clues (clues available from the input of just one eye) and binocular clues (clues that require input from both eyes).
