Single image dehazing motivated by Retinex theory
2013 2nd International Symposium on Instrumentation and Measurement, Sensor Network and Automation (IMSNA), 2013Haze removal from a degraded image which is attenuated by the turbid media in the atmosphere is an important task in image and video processing. From a computer vision perspective, this task is extremely challenging because the haze is dependent on the unknown depth information, and will be under-constrained if only one single haze image is input.

An Image Enhancement Algorithm Based on Retinex Theory
2009 First International Workshop on Education Technology and Computer Science, 2009According to the Retinex theory, the color of an object is jointly decided by its reflecting ability to three independent wave-length lights-lights of short, medium, and long wave. The reflecting ability of the object in a certain wave band is an immanence nature which does not rely on lamp-house itself.

Parabolic Adjustment of Image Clearness Algorithm Based on Retinex Theory
2011 Seventh International Conference on Computational Intelligence and Security, 2011If the histogram equalization on the basis of Retinex theory is used to an image, an excessive enhancement or darkening of brightness may arise. Aimed at these problems, this paper presents a parabolic adjustment of image clearness algorithm, which is mainly based on Retinex theory, equalizing histogram with the aid of parabolic transfer function ...

A 18.42 times faster video encoder based on Retinex theory
2012 Picture Coding Symposium, 2012Because of the limitation in the imaging system, videos captured by mobile devices are usually noisy. In this paper, a noise robust fast video encoding scheme is proposed based on Retinex theory. The reflectance image is estimated in a co-analysis module by Retinex theory, within which the content similarity is detected to conduct the encoding process.

Color Vision and Retinex Theory
1988It is a cultural commonplace deriving from Newton that the color of an object in the world around us depends on the relative amounts of red, green, and blue light Coming from the object to our eyes. In contradiction, it has long been known that the color of an object when it is part of a general scene will not change markedly with those considerable ...

Low-Light In-Room Image Enhancement Network Based on Retinex Theory
2024 5th International Conference on Information Science and Education (ICISE-IE)Taking pictures indoors always faces low light and high number of shadows, and because of the complexity of the light source, it indirectly leads to more noise in indoor images than in images captured from outdoor scenes.

Image Enhancement Algorithm for Cold Cathode Weld Defect Based on Improved Retinex Theory
2024 6th International Conference on Intelligent Control, Measurement and Signal Processing (ICMSP)To address the issues of low contrast and poor visual quality in cold cathode weld defect images, an image enhancement algorithm based on an improved Retinex theory is proposed. First, bilateral filtering is used to remove stripe noise in the image. Next,
