Implementation and application of Retinex algorithms to the preprocessing of retinography color images [PDF]

, 2009
La retinopatía diabética es una enfermedad causada por complicaciones de la retina, con evolución progresiva. Esta patología se detecta en las imágenes de fondo de ojo que, en la mayoría de los casos, presentan iluminación no uniforme.

Analysis of retinal and cortical components of Retinex algorithms

, 2017
Following Land and McCann’s first proposal of the Retinex theory, numerous Retinex algorithms that differ considerably both algorithmically and functionally have been developed.

From samples to populations in retinex models [PDF]

, 2017
Some spatial color algorithms, such as Brownian Milano retinex (MI-retinex) and random spray retinex (RSR), are based on sampling. In Brownian MI-retinex, memoryless random walks (MRWs) explore the neighborhood of a pixel and are then used to compute its

Formalizations of the Retinex model and its variants with variational principles and partial differential equations

, 2017
Edwin H. Land and John J. McCann introduced the Retinex model as a computational theory of color vision. However, Retinex details were described rather algorithmically than mathematically.

A Multi-Scale Fusion Strategy for Side Scan Sonar Image Correction to Improve Low Contrast and Noise Interference

Remote Sensing
Side scan sonar images have great application prospects in underwater surveys, target detection, and engineering activities. However, the acquired sonar images exhibit low illumination, scattered noise, distorted outlines, and unclear edge textures due ...

Unifying Path and Center-surround Retinex Algorithms [PDF]

Retinex is a theory of colour vision, and it is also a well known image enhancement algorithm. The Retinex algorithms reported in the literature are often called path-based or centre surround.

Improved Low-Light Image Feature Matching Algorithm Based on the SuperGlue Net Model

Remote Sensing
The SuperGlue algorithm, which integrates deep learning theory with the SuperPoint feature extraction operator and addresses the matching problem using the classical Sinkhorn method, has significantly enhanced matching efficiency and become a prominent ...

SuPeR: Milano Retinex implementation exploiting a regular image grid

, 2019
A spatial color algorithm grounded on the Retinex theory is known as a Milano Retinex. This type of algorithm performs image enhancement by processing spatial and color cues in the neighborhood of each image pixel. Because this local, pixel-wise analysis
