Gauss-Seidel Retinex

open access: yesJournal of Physics: Conference Series
Abstract Retinex has many algorithmic variants, differing in the method used to decouple illumination from reflectance, including path-based methods, center-surround operators, and lightness processing. The center-surround approach is putatively the most compatible with the human visual mechanism, as it mimics the operation in ...

Retinex-qDPC: automatic background rectified quantitative differential phase contrast imaging [PDF]

open access: yes, 2022
The quality of quantitative differential phase contrast reconstruction (qDPC) can be severely degenerated by the mismatch of the background of two oblique illuminated images, yielding problematic phase recovery results.

A Review of Remote Sensing Image Dehazing

open access: yesSensors, 2021
Remote sensing (RS) is one of the data collection technologies that help explore more earth surface information. However, RS data captured by satellite are susceptible to particles suspended during the imaging process, especially for data with visible ...

Retinex mine image enhancement algorithm based on TopHat weighted guided filtering

open access: yesGong-kuang zidonghua, 2022
The uneven distribution of light sources and weak light in coal mines lead to low brightness and unclear image. The traditional Retinex algorithm has the problems of detail loss, edge blur and halo when processing low illumination images of coal mines ...

Tuning Retinex parameters [PDF]

open access: yesJournal of Electronic Imaging, 2004
Our goal is to understand how the Retinex parameters affect the predictions of the model. A simplified Retinex computation is specified in the recent MATLAB TM implementation; however, there remain several free parameters that introduce significant variability into the model's predictions. We extend previous work on specifying these parameters.
