Underwater Image Restoration via Adaptive Color Correction and Contrast Enhancement Fusion
Remote Sensing, 2023 When light traverses through water, it undergoes influence from the absorption and scattering of particles, resulting in diminished contrast and color distortion within underwater imaging.

Real-time Model-based Image Color Correction for Underwater Robots [PDF]
IEEE/RJS International Conference on Intelligent RObots and Systems, 2020 Recently, a new underwater imaging formation model presented that the coefficients related to the direct and backscatter transmission signals are dependent on the type of water, camera specifications, water depth, and imaging range.

Three-Color Balancing for Color Constancy Correction [PDF]
Journal of Imaging, 2021 This paper presents a three-color balance adjustment for color constancy correction. White balancing is a typical adjustment for color constancy in an image, but there are still lighting effects on colors other than white. Cheng et al. proposed multi-color balancing to improve the performance of white balancing by mapping multiple target colors into ...

Enhancement of Underwater Images with Retinex Transmission Map and Adaptive Color Correction
Applied Sciences, 2023 Underwater images often suffer from low contrast, low visibility, and color deviation. In this work, we propose a hybrid underwater enhancement method consisting of addressing an inverse problem with novel Retinex transmission map estimation and adaptive

DeepSeeColor: Realtime Adaptive Color Correction for Autonomous Underwater Vehicles via Deep Learning Methods [PDF]
IEEE International Conference on Robotics and Automation, 2023 Successful applications of complex vision-based behaviours underwater have lagged behind progress in terrestrial and aerial domains. This is largely due to the degraded image quality resulting from the physical phenomena involved in underwater image ...

Underwater Image Enhancement Based on Adaptive Color Correction and Improved Retinex Algorithm
IEEE Access, 2023 In order to solve the problems about color distortion and low contrast of underwater images, we propose an underwater image enhancement algorithm that combines adaptive color correction with improved Retinex algorithm.

Corrections to Estimated Accretion Disk Size due to Color Correction, Disk Truncation, and Disk Wind [PDF]
Astrophysical Journal Letters, 2022 We consider three corrections to the disk sizes estimated at a given frequency using accretion models. They are due to a color correction, a disk truncation at an inner radius larger than the innermost stable circular orbit, and disk winds, which we ...
