The human visual system (HVS), affected by viewing distance when perceiving the stereo
image information, is of great significance to study of stereoscopic image quality …

The task of underwater image enhancement aims to improve the quality of the images and
promote the visualization effect. Current methods still face some challenges, which include …

In this paper, two newly proposed evolutionary computational algorithms (ECAs) are joined
with Otsu thresholding method to achieve brightness preserving image contrast …

Underwater color images suffer from low visibility and color cast effects caused by light
attenuation by water and floating particles. This study applied single image enhancement …

MRI is one of the most compliant technique that is used for the screening of Brain Tumor.
MRI can be acquired in four available modalities which are MR-T1, MR-T2, MR-PD and MR …

In this paper, we introduce a new spatial domain color contrast enhancement algorithm
based on the alpha weighted quadratic filter. The goal of this work is to utilize the …

In low illumination situations, insufficient light in the monitoring device results in poor
visibility of effective information, which cannot meet practical applications. To overcome the …

Traditional dehazing methods based on restoration are prone to color distortion and noise
amplification when dealing with hazy image with large sky area. To improve dehazing effect …

In this paper, a novel image contrast enhancement method based on the histogram
specification concept is presented. The proposed algorithm first, models the input image's …

Image enhancement algorithms are commonly used to increase the contrast and visual
quality of low-dose x-ray images. This paper proposes an automated enhancement method …
