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 ...

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 ...

Manufacturers are adopting automated optical inspection (AOI) systems based on phase shift profilometry (PSP) for applications in advanced packaging processes. Many of these processes use front ...

Last July, a glint of sunlight from Saturn’s moon Titan sped through space and fell upon the sensors of the Cassini spacecraft, starting a process of discovery that is now strengthening the idea that ...
