a, An axi-symmetric binary phase filter (BPF) and image reconstruction network are jointly learned through the physics-informed neural network. The learned BPF is fabricated and inserted in a pupil ...

A picture is worth a thousand words -but only when it's clear what it depicts. And therein lies the rub in making images or videos of microscopic life. While modern microscopes can generate huge ...

A series of short-exposure images are often used for rich, small-scale structure, high-quality, and high-resolution astronomical observations. Postprocessing of the closed-loop adaptive optics (AO) ...

Scientists have devised deep-learning and other approaches that dramatically reduce image-analysis times by orders of magnitude -- in some cases, matching the speed of image data acquisition itself. A ...
