This is the depth cue known as binocular (retinal) disparity. The brain compares these two images as part of depth perception. The impression of depth created by binocular disparity is called stereopsis. It can be used to create an illusion of depth in a picture using special viewing devices or glasses. October …
WebThe relationship between object size and distance is an inverse linear relationship, i.e. size is 1 / distance. This makes sense when you think about it as if you double the distance the size halves. This is why you appear to be observing an exponential: the exponent is -1, if you take the reciprocal of the size, your graph should be a straight ...
