Validation of Skin Perfusion Monitoring by Imaging PPG versus Laser Speckle Imaging

Current Directions in Biomedical Engineering, 2023
Assessment of skin perfusion can reveal signs of deterioration and help to prevent critical states. Commonly applied clinical tests to capture skin perfusion are subjective and often hard to quantify.

Impact of the Coupling and Coordinated Development of National and Global Value Chains on Green Development: Evidence from China’s Manufacturing Industry

Systems
Against the backdrop of China’s new development paradigm, this study examines how the coupling coordination between the national value chain (NVC) and the global value chain (GVC) affects regional green development and the mechanisms through which it ...

Decision-Based Demosaicking Algorithm Using Bayesian Theorem

IEEE Access, 2018
In this paper, we introduce a new color filter array interpolation based on edge map prediction using the Bayesian theorem. The edge information obtained at the position of the green component sampled in the quincunx grid using the Bayer pattern is used ...

Asymmetric color image encryption and compression based on discrete cosine transform in Fresnel domain

Results in Optics, 2020
In this paper, a new asymmetric method is presented to encrypt and compress color images using discrete cosine transform in Fresnel domain. First, the input color image is decomposed into three channels: red, green and blue.

Converting TREx-RGB green-channel data to 557.7 nm auroral intensity: Methodology and initial results

Earth and Planetary Physics
The recently deployed Transition Region Explorer (TREx)-RGB (red-green-blue) all-sky imager (ASI) is designed to capture “true color” images of the aurora and airglow.

Color Image Denoising Using The Green Channel Prior

CoRR
Noise removal in the standard RGB (sRGB) space remains a challenging task, in that the noise statistics of real-world images can be different in R, G and B channels. In fact, the green channel usually has twice the sampling rate in raw data and a higher signal-to-noise ratio than red/blue ones.

Exact construction and uniqueness of the coupled-channel Green's function

Physical Review C
We present a rigorous construction and uniqueness proof of the matrix Green's function for coupled radial Schrödinger equations with symmetric coupling potentials. The Green's matrix $g_{γγ'}(R,R')$ is built from two fundamental sets of $N$ linearly independent solutions, regular and outgoing, of the coupled radial equations.
