Automatic Contrast-Limited Adaptive Histogram Equalization With Dual Gamma Correction

IEEE Access, 2018
We propose automatic contrast-limited adaptive histogram equalization (CLAHE) for image contrast enhancement. We automatically set the clip point for CLAHE based on textureness of a block.

Contrast Enhancement of Brightness-Distorted Images by Improved Adaptive Gamma Correction

, 2017
As an efficient image contrast enhancement (CE) tool, adaptive gamma correction (AGC) was previously proposed by relating gamma parameter with cumulative distribution function (CDF) of the pixel gray levels within an image.

Visual Contrast Enhancement Algorithm Based on Histogram Equalization

Sensors, 2015
Image enhancement techniques primarily improve the contrast of an image to lend it a better appearance. One of the popular enhancement methods is histogram equalization (HE) because of its simplicity and effectiveness.

Color enhancement of landsat agricultural imagery: JPL LACIE image processing support task [PDF]

Color enhancement techniques were applied to LACIE LANDSAT segments to determine if such enhancement can assist analysis in crop identification. The procedure involved increasing the color range by removing correlation between components.

Denoising Autoencoder and Contrast Enhancement for RGB and GS Images with Gaussian Noise

Mathematics
Robust image processing systems require input images that closely resemble real-world scenes. However, external factors, such as adverse environmental conditions or errors in data transmission, can alter the captured image, leading to information loss ...

FUZZY BASED CONTRAST STRETCHING FOR MEDICAL IMAGE ENHANCEMENT [PDF]

ICTACT Journal on Soft Computing, 2011
Contrast Stretching is an important part in medical image processing applications. Contrast is the difference between two adjacent pixels. Fuzzy statistical values are analyzed and better results are produced in the spatial domain of the input image. The

Underwater Image Enhancement via RGB Color-Cast Correction and Lab Space Luminance-Chrominance Enhancement

Journal of Marine Science and Engineering
Underwater images often suffer from color casts, insufficient contrast, and blurred details due to wavelength-dependent absorption and scattering, which limits their use in marine observation and underwater target recognition.

DCT Underwater Image Enhancement Based on Attenuation Analysis

Sensors
Underwater images often suffer from color distortion, reduced contrast, and blurred details due to the selective absorption and scattering of light by water, which limits the performance of underwater visual tasks.
