Implicit Neural Speckle Denoising
Matthew R. Ziemann, Casey J. Pellizzari, Tyler J. Hardy +1
Speckle fundamentally limits coherent imaging by introducing multiplicative, spatially correlated noise that obscures scene structure. Removing speckle noise from dynamic scenes--t…
Inverse Synthetic Aperture Fourier Ptychography
Matthew A. Chan, Casey J. Pellizzari, Christopher A. Metzler
Fourier ptychography (FP) is a powerful light-based synthetic aperture imaging technique that allows one to reconstruct a high-resolution, wide field-of-view image by computational…
Dynamic DH-MBIR for Phase-Error Estimation from Streaming Digital-Holography Data
Ali G. Sheikh, Casey J. Pellizzari, Sherman J. Kisner +2
Directed energy applications require the estimation of digital-holographic (DH) phase errors due to atmospheric turbulence in order to accurately focus the outgoing beam. These pha…
Phase-error estimation and image reconstruction from digital-holography data using a Bayesian framework
Casey J. Pellizzari, Mark F. Spencer, Charles A. Bouman
The estimation of phase errors from digital-holography data is critical for applications such as imaging or wave-front sensing. Conventional techniques require multiple i.i.d. data…
