A unified Benchmark for Multi-Frame Image Restoration under Severe Refractive Warping
Maxim V. Shugaev, Md Reshad Ul Hoque, Bridget Kennedy +8
Video sequence capturing through refractive dynamic media, such as a turbulent air or water surface, often suffer from severe geometric distortions and temporal instability. While…

Visible to Longwave-infrared imaging via an inverse-designed monolithic lens
Syed N. Qadri, Apratim Majumder, John D. Hodges +3
Chromatic aberrations impose a fundamental barrier on optical design, confining most imaging systems to narrow spectral bands with fractional bandwidths typically limited to $Îλ/…

HD snapshot diffractive spectral imaging and inferencing
Apratim Majumder, Monjurul Meem, Fernando Gonzalez del Cueto +4
We present a novel high-definition (HD) snapshot diffractive spectral imaging system utilizing a diffractive filter array (DFA) to capture a single image that encodes both spatial…
