Pupil Design for Computational Wavefront Estimation
Ali Almuallem, Nicholas Chimitt, Bole Ma +2
Establishing a precise connection between imaged intensity and the incident wavefront is essential for emerging applications in adaptive optics, holography, computational microscop…
Learning Phase Distortion with Selective State Space Models for Video Turbulence Mitigation
Xingguang Zhang, Nicholas Chimitt, Xijun Wang +2
Atmospheric turbulence is a major source of image degradation in long-range imaging systems. Although numerous deep learning-based turbulence mitigation (TM) methods have been prop…
Person Recognition at Altitude and Range: Fusion of Face, Body Shape and Gait
Feng Liu, Nicholas Chimitt, Lanqing Guo +16
We address the problem of whole-body person recognition in unconstrained environments. This problem arises in surveillance scenarios such as those in the IARPA Biometric Recognitio…
Wavefront Estimation From a Single Measurement: Uniqueness and Algorithms
Nicholas Chimitt, Ali Almuallem, Qi Guo +1
Wavefront estimation is an essential component of adaptive optics where the goal is to recover the underlying phase from its Fourier magnitude. While this may sound identical to cl…
Computational Imaging Through Atmospheric Turbulence
Nicholas Chimitt, Stanley H. Chan
Since the seminal work of Andrey Kolmogorov in the early 1940's, imaging through atmospheric turbulence has grown from a pure scientific pursuit to an important subject across a mu…
