Night Image Enhancement by means of Retinex Filtering

open access: yes, 2020
This is the fourth work of a series which is showing applications of Retinex filters. In the first paper, we considered the images from microscopes. In the second, we discussed how a Retinex filtering can help us in the investigation of the motion of ...

Retinex filtering and thresholding of foggy images [PDF]

open access: yes, 2015
Recently, we have discussed the use of GIMP Retinex, a filter of the GNU Image Manipulation Program, for enhancing images in several applications, ranging from those obtained by microscopes to the images coming from satellites.

A nighttime image enhancement method based on Retinex and guided filter for object recognition of apple harvesting robot

open access: yesInternational Journal of Advanced Robotic Systems, 2018
In order to improve the working efficiency of robot promptly picking ripe apples, the harvesting robot must have the ability of continuous recognition and operation at night. Nighttime apple image has many dark spaces and shadows with low resolution, and

Retinex theory-based shadow detection and removal in single outdoor image

open access: yes, 2009
Shadows, the common phenomena in most outdoor scenes, bring many problems in practical image processing. Shadow detection and removal, especial in uncalibrated outdoor image, is still a difficult problem.

Point-based Spatial Color Sampling in Milano-Retinex : a Survey

open access: yes, 2018
Milano-Retinex is a family of Retinex-inspired spatial colour algorithms mainly developed for colour image enhancement. According to the Retinex theory, a Milano-Retinex algorithm takes as input an RGB image and processes the colour intensities of each ...

A mixed enhancement algorithm of video monitoring image on fully-mechanized coal mining face

open access: yesGong-kuang zidonghua, 2016
In view of problem of longitudinal stripe noise existed in single dimension Retinex algorithm, a mixed enhancement algorithm of image was proposed. The algorithm uses template denoising algorithm to reduce longitudinal stripe noise of conventional single
