DOI: 10.1016/j.optlaseng.2019.105826

Abstract: Abstract We propose a simultaneous noise filtering and phase unwrapping algorithm. Spatial evolution of phase is modeled as an autoregressive Gaussian Markov random field. Accordingly, phase value at a pixel is related to phase values… read more here.

DOI: 10.1063/5.0019209

Abstract: A low-pass filtering compensation (LPFC) method is proposed to compensate for phase aberrations in point diffraction-based common-path digital holographic microscopy. This method estimates the phase aberration from the object hologram by Fourier transform and low-pass… read more here.

DOI: 10.1109/toh.2023.3273168

Abstract: We study the effect of low-pass filtering on the passivity and performance of series elastic actuation (SEA) under velocity-sourced impedance control (VSIC) while rendering virtual linear springs and the null impedance. We analytically derive the… read more here.

DOI: 10.1111/jog.16006

Abstract: The aim of this study is to investigate whether the results of pelvimetry using original radiographic Martius images and the same images with high‐pass filtering applied (“edge images”) would be consistent. read more here.
