Measuring image quality made easier with new computational methods

Researcher Mikko Nuutinen has developed methods for measuring the quality of digital and printed images computationally with algorithms directly from natural images. These unprecedented methods are presented in his doctoral ...

Nanoantennas help detectors see more heat, less noise

Sandia National Laboratories researchers have developed tiny, gold antennas to help cameras and sensors that "see" heat deliver clearer pictures of thermal infrared radiation for everything from stars and galaxies to people, ...

Dragonfly eyes inspire new microlens array processing technique

Industry 4.0 requires simple solutions for complex functions. Optical sensors, such as pinhole cameras, can deliver a depth of focus and reasonable resolution, but they suffer from low intensity for reliable and fast imaging. ...

Video chat expands possibilities for face-to-face services

You once had to leave home to see a psychiatrist for therapy, a music teacher for guitar lessons or a makeup artist for face-to-face consultations. Now they can come to you, virtually, through video chat.
