Orthogonal matching pursuit vs. iterative hard thresholding: addressing phase discontinuities in digital holography
Yue Wang,
John Healy
Abstract:This paper presents a novel comparative study between two prominent compressed sensing algorithms -Orthogonal Matching Pursuit (OMP) and Iterative Hard Thresholding (IHT) -within the context of digital holography, specifically focusing on their efficacy in handling phase discontinuities. Previous research has predominantly centered on Gibbs ringing artifacts in image reconstruction and their mitigation. However, the aspect of phase discontinuities, which are critical in holographic imaging, has not been extens… Show more
