2025年1月1日 · With regard to polarimetric image denoising, non-local self-similarity is an important characteristic of natural images [12], and also an effective prior for image restoration. Concretely, a given patch in an image is likely to be found elsewhere in the same image, therefore each noisy patch could help to denoise the other noisy patches.

2019年2月1日 · Polarimetric observations of aerosol properties have also been implemented by ground-based radiometer networks. In addition, several in situ and laboratory polar-nephelometer systems have been designed for accurate measurements of spectral, angular, and polarimetric characteristics of light singly scattered by aerosol particles.

Expectedly, polarimetric decomposition technique is the most effective avenue to this task. Among polarimetric decomposition methods, the model-based polarimetric decomposition methods first proposed by Freeman (F3D) (Freeman and Durden, 1998) and Yamaguchi (Y4D) (Yamaguchi et al., 2005) are the most typical. In this category, the measured ...

2010年6月23日 · Among the polarimetric features, which refer to the wave polarization properties instead of polarimetric scattering properties, the most used are: wave entropy and degree of polarization, H w and P w, respectively, the complex correlation coefficient between the two orthogonal components of the received wave, ρ w, the ellipticity parameter, χ ...

2010年11月15日 · This pair of invariant, non-dimensional, indices of polarimetric purity contains complete information about the polarimetric purity of a light beam. The overall degree of polarimetric purity is obtained as a weighted quadratic average of the degree of polarization and the degree of directionality.

2024年11月14日 · Despite such advancements, the polarizer in polarimetric PDs inherently diminishes the incident light intensity, potentially compromising the PD sensitivity. 15 Researchers have constructed polarizer-free polarimetric PDs from various organic and inorganic materials, including organic semiconductors, 4, 6, 16 carbon nanotubes, 17 two-dimensional (2D) …

2025年2月1日 · Geo-NeuS is a method that combine MVS and NeRF together to achieve good reconstruction. Lastly, Polarimetric MVIR and PANDORA leverages geometric, photometric, and polarimetric cues from multi-view color and polarization images to reconstruct detailed 3D shapes without assuming specific surface material or lighting conditions.

2023年3月15日 · In this manuscript, we have defined the polarimetric scenario of GNSS-R reflections retrieved by SMAP-R over land. The polarimetric spaceborne GNSS-R signals have been interpreted using the four Stokes parameters, presenting for the first time a unique and unprecedented view of polarimetric L-band forward scattering from Earth's surface.

2024年12月1日 · Polarimetric Synthetic Aperture Radar (PolSAR) is an advanced imaging technique adept at generating high-resolution images of the Earth by measuring the polarimetric scattering traits of targets (Chen et al., 2019, Hu et al., 2017). By actively transmitting and receiving electromagnetic waves of different polarimetric states, PolSAR acquires ...

2023年9月1日 · It is also worth mentioning that the polarimetric data collected by the UK radar network has been exploited by many researchers to develop polarimetric-based weather radar algorithms with the primary goal of improving radar QPE products (e.g. Bringi et al., 2011, Hall et al., 2015, Jewell and Gaussiat, 2015, Liguori et al., 2012, Pickering et ...
