A PDE Formalization of Retinex Theory
IEEE Transactions on Image Processing, 2010In 1964 Edwin H. Land formulated the Retinex theory, the first attempt to simulate and explain how the human visual system perceives color. His theory and an extension, the "reset Retinex" were further formalized by Land and McCann. Several Retinex algorithms have been developed ever since. These color constancy algorithms modify the RGB values at each

Color constancy effects measurement of the Retinex theory.
, 1999 Understanding chromatic adaptation is a necessary step to solve the color constancy problem for a variety of application purposes. Retinex theory justifies chromatic adaptation, as well as other color illusions, on visual perception principles. Based on the above theory, we have derived an algorithm to solve the color constancy problem and to simulate ...

Color Vision Is a Spatial Process: The Retinex Theory
, 2017 Born through the work of Edwin H. Land and John J. McCann more than 40 years ago, Retinex theory proposes a computational model to explain and estimate the human color sensation, i.e. the color perception that human vision system produces when oberving a scene.

Eye detection under varying illumination using the retinex theory
Neurocomputing, 2013Eye detection plays an important role in face recognition because eyes provide distinctive facial features. However, illumination effects such as heavy shadows and drastic lighting change make it difficult to detect eyes well in facial images. In this paper, we propose a novel framework for illumination invariant eye detection under varying lighting ...

Analysis of the retinex theory of color vision
Journal of the Optical Society of America A, 1986If color appearance is to be a useful feature in identifying an object, then color appearance must remain roughly constant when the object is viewed in different contexts. People maintain approximate color constancy despite variation in the color of nearby objects and despite variation in the spectral power distribution of the ambient light.

Influence Theory for Retinex Models
Topical Meeting on Color Appearance, 1987The color constancy problem is one of calculating reflectance values for surfaces under differing illuminants. Retinex theory (e.g., Land, 1986) states that relative receptor responses are used to recover surface reflectance after they have been normalized with respect to the responses of neighboring receptor responses.

Enhancement of Infrared Image Based on the Retinex Theory
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007The infrared imaging technique can be used to image the temperature distribution of the body. It's hopeful to be applied to the diagnosis and prediction of many diseases. Image processing is necessary to enhance the original infrared images because of the blurring.
