Smooth surfaces, as polished, coated, or wet surfaces, produce specular reflections under unfavourable lighting conditions. Image processing algorithms, such as any correlation-based computation, may ...

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 ...

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 ...
