Low-Light Image Enhancement Using CNN and Bright Channel Prior

2017 IEEE International Conference on Image Processing (ICIP), 2017
In this paper, we propose a joint framework to enhance images under low-light conditions. First, a convolutional neural network (CNN) based architecture is proposed to denoise low-light images. Then, based on atmosphere scattering model, we introduce a low-light model to enhance image contrast.

Effects of precipitation and cloud ice on brightness temperatures in AMSU moisture channels

IEEE Transactions on Geoscience and Remote Sensing, 1997
Extinction by ice and rain at the AMSU frequencies used in water vapor profile retrievals is investigated with DMSP observations and brightness temperature simulations of a convective storm system. The simulations are based on mesoscale forecast model output of atmospheric, cloud, and rain profiles from which the absorption and scattering due to both ...

Radar-Bright Channels on Titan

2009
The Cassini SAR observed channels in the Xanadu region of Titan which exhibit very large radar cross-sections. We propose the presence of (transparent) rounded, icy rocks with size larger than the radar wavelength (2.18 cm) to explain observations.

Image Defogging algorithm Based on Image Bright and Dark Channels

2018 WRC Symposium on Advanced Robotics and Automation (WRC SARA), 2018
This paper proposes an image defogging algorithm based on the combination of bright and dark channel in fog and haze weather. A model of the air light scattering is proposed based on the physical model of degraded image. Air light value and transmissivity are estimated by using the combination of light channel prior and dark channel prior.

The Bright Side of Price Guarantee for Retailers in a Decentralized Distribution Channel

Managerial and Decision Economics
ABSTRACTOnline retailers usually refund the price difference to consumers after a product price reduction, which is known as price guarantee. This paper delves into the implications of price guarantee within supply chains that integrate one manufacturer, one retailer, and consumers within two sale periods. Employing a game model, we first find that the
