Binocular stereopsis is a powerful visual depth cue. To exploit it, the brain matches features from the two eyes' views and measures their interocular disparity. This works well for matte surfaces ...

Glints of light from specular reflection of the Sun are a technosignature of artificial satellites. If extraterrestrial intelligences have left artifacts in the Solar System, these may include flat ...

The field of visual perception and material recognition examines how the human visual system deciphers the physical properties of objects—from their texture and gloss to subtle variations in surface ...
