Gaussian blurring provides the illusion of depth in the figures below. The first, nonblurred figure appears flat while the others show some depth. Look at the images with both eyes and then with each eye. Does blurring provide a monocular or binocular cue to depth?
Compare the figures on the various backgrounds. Does the illusion of depth appear equal for all figures or is it enhanced by some backgrounds?
Below, in the figure on the left, Gaussian blur and interposition provide monocular cues to depth. Interposition refers to the blue figure appearing to block the view of the continuous lines. In the right image, perspective and relative position have been added as monocular cues. For which image is the illusion of depth stronger?
