Efficient Dark Channel Prior Based Blind Image De-blurring [PDF]

open access: yesRadioengineering, 2021
Dark channel prior for blind image de-blurring has attained considerable attention in recent past. An interesting observation in blurring process is that the value of dark channel increases after averaging with adjacent high intensity pixels.

Dark response by color channel.

open access: yes, 2013
A) Dark response used for dark subtraction during image processing. For image exposure times below or equal to , the dark response for a given color channel (red, green, blue; plot colors correspond to the three color channels) was taken as the median ...

Multispectral Image Enhancement Based on the Dark Channel Prior and Bilateral Fractional Differential Model

open access: yesRemote Sensing, 2022
Compared with single-band remote sensing images, multispectral images can obtain information on the same target in different bands. By combining the characteristics of each band, we can obtain clearer enhanced images; therefore, we propose a ...

Generalization of the Dark Channel Prior for Single Image Restoration [PDF]

open access: yesIEEE Transactions on Image Processing, 2018
Images degraded by light scattering and absorption, such as hazy, sandstorm, and underwater images, often suffer color distortion and low contrast because of light traveling through turbid media. In order to enhance and restore such images, we first estimate ambient light using the depth-dependent color change.

Image Mosaic Based on Local Guidance and Dark Channel Prior

open access: yesImage Analysis and Stereology
Image mosaic is of significance in various areas such as object tracking and drone reconnaissance. Aiming at the problems of poor performance and high rate of false match in foggy images, an improved stitching method based on local guided KAZE and dark ...

An image dust removal and enhancement method in low illumination environment based on dark-bright channel segmentation and fusion

open access: yesMeitan xuebao
Due to the influence of dust, water mist and low illumination environment in coal mine, it is very difficult to accurately identify the monitoring images of belt transportation system. Aiming at the problem of poor image processing results and efficiency

Probing dark matter particles at CEPC

open access: yesJournal of High Energy Physics, 2019
We investigate the capability of the future electron collider CEPC in probing the parameter space of several dark matter models, including millicharged dark matter models, Z ′ portal dark matter models, and effective dark matter operators.

Simplified Models for Dark Matter Searches at the LHC [PDF]

open access: yes, 2015
This document outlines a set of simplified models for dark matter and its interactions with Standard Model particles. It is intended to summarize the main characteristics that these simplified models have when applied to dark matter searches at the LHC ...

Hybrid Dark Channel Prior for Image Dehazing Based on Transmittance Estimation by Variant Genetic Algorithm

open access: yesApplied Sciences, 2023
Image dehazing has always been one of the main areas of research in image processing. The traditional dark channel prior algorithm (DCP) has some shortcomings, such as incomplete fog removal and excessively dark images.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
