A Novel Approach to Underwater De-Scattering Based on Sparse and Low-Rank Matrix Decomposition

Underwater Multispectral Computational Imaging Based on a Broadband Water-Resistant Sb2Se3 Heterojunction Photodetector

“…With regard to the first issue of blurring imaging caused by scattering, the traditional way of solving the scattering problem is to propose polarization imaging methods − and image algorithm methods. − However, the above methods do not perform well in extreme weak-light environment. Fortunately, single-photodetector computational imaging (also named as ghost imaging or single-pixel imaging in some field), as a computational imaging technology that has only been developed for a decade, , exhibits excellent antiscattering underwater imaging capability, so it has attracted a significant interest in the field of underwater imaging. − In contrast to a commercial silicon-based charge-coupled device (CCD) and complementary metal–oxide–semiconductor (CMOS) cameras, the most advanced single-photodetector imaging system (such as Fourier and Hadamard single-pixel imaging) can capture a scene using programmed structured lights and a single photodetector (PD) without spatial resolution.…”
