Contrast Enhancement in 2D Nanomaterial SEM Images
Engineering ProceedingsOwing to their large size and flexibility, 2D nanostructures (e.g., graphene, graphene oxide, single-layer molybdenum disulfide, etc.) are technologically exploited in a supported form. Glass, silicon, and polymers are typical substrates.

Joint Noise Reduction for Contrast Enhancement in Stokes Polarimetric Imaging
IEEE Photonics Journal, 2019 Contrast optimization is a key issue in polarimetric imaging for the purpose of target detection. In practice, the noise could induce the intensity fluctuation of the image and thus lead to the decrease of the image contrast.

A Critical Analysis on Perceptual Contrast and Its Use in Visual Information Analysis and Processing
IEEE Access, 2020 Contrast in visible images is one of the most relevant characteristics of visual signals. Since the pioneering works performed in vision psychology and optics, different definitions have been proposed in the literature.

Contrast Enhancement for Topographic Imaging in Confocal Laser Scanning Microscopy
Applied Sciences, 2019 The influence of the axial pinhole position in a confocal microscope in terms of the contrast of the image is analyzed. The pinhole displacement method is introduced which allows to increase the contrast for topographic imaging.

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.

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.

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