Dark and Bright Channel Priors for Haze Removal in Day and Night Images

Intelligent Automation & Soft Computing, 2022
Removal of noise from images is very important as a clear, denoised image is essential for any application.In this article, a modified haze removal algorithm is developed by applying combined dark channel prior and multi-scale retinex theory.The combined dark channel prior (DCP) and bright channel prior (BCP) together with the multi-scale retinex (MSR)

The bright side of online recycling: Perspectives of customer’s channel preference and competition

Electronic Commerce Research and Applications, 2021
Abstract Online recycling has gradually become an effective way for remanufacturers in collecting used products. Meanwhile, this new recycling business model complicates the marketing and operational decisions for firms in the reverse supply chain (RSC). This study focuses a RSC which consists of a remanufacturer and a recycler.

Simulating brightness temperatures at SSM/I channels in the Mediterranean area

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
An accurate retrieval of atmospheric and sea surface parameters from spaceborne microwave radiometers requires to validate the radiative forward model capable to simulate the brightness temperatures for known atmospheric and surface conditions. Matching the forward model and the retrieval algorithm to the climatological condition of the area of ...

Unsupervised Low-Light Image Enhancement Using Bright Channel Prior

IEEE Signal Processing Letters, 2020
Recent approaches for low-light image enhancement achieve excellent performance through supervised learning based on convolutional neural networks. However, it is still challenging to collect a large amount of low-/normal-light image pairs in real environments for training the networks.

Brightness estimation supports a two-channel model of achromatic brightness processing

Annual Meeting Optical Society of America, 1986
Brightness magnitude estimation functions for 3400° white circular increments on a 2700° white 38 cd/m2 background were measured on a modified Tubingen perimeter. The stimuli ranged from 1.7′ to 66′ in diameter, 0.07-1 s in duration, and 0° to 20° in eccentricity. Brightness estimates were obtained at 0.2 log unit luminance intervals from the increment

Correlation between Brightness and Channel Currents of Electrical Discharges

IEEE Transactions on Dielectrics and Electrical Insulation, 2007
Channel brightness of 500 mm long electrical discharges were measured by analyzing a set of digitized images taken by 3 cameras placed symmetrically around a discharge gap at a radial distance of 200 cm from the axis of the spark. The sparks were generated between a steel rod and a plane electrode.

Contribution of chromatic channels to brightness: effects of retinal Illuminance

Annual Meeting Optical Society of America, 1988
Spectral luminous efficiency functions were measured by direct heterochromatic brightness matching and flicker photometry at the retinal illuminance levels, 1, 10, 100, and 1000 trolands with a 2° visual field. For all four subjects, as the retinal illuminance increases, the luminous efficiency curves for heterochromatic brightness matching broaden ...

Intercalibration of NOAA and Meteosat window channel brightness temperatures

International Journal of Remote Sensing, 2005
This study presents an intercalibration of Meteosat‐5 11 µm channel and NOAA‐14 10.8 µm and 12.0 µm channels, and their comparison for sea and land pixels. The intercalibration empirical relation is derived for clear‐sky sea measurements, with similar zenith viewing angles.
