In this article, a novel low-light image enhancement (LIME) using reflection model and
principal component analysis (PCA) has been proposed. The proposed algorithm works …

In this paper, a neoteric tripartite sub-image histogram equalization method is proposed to
enhance slightly low contrast gray-tone images, which is a less explored area in the …

Improving the quality of medical images is helpful for doctors to perform clinical diagnosis
and treatment. Many medical image enhancement methods can achieve good performance …

The histogram equalization approach, which is employed for image enhancement, reduces
the number of pixel intensities, resulting in detail loss and an unnatural impression. This …

Image enhancement by histogram equalization reduces the number of gray levels that lead
to information loss and unnatural appearance. This paper aims to improve the contrast and …

Many vision-based systems suffer from poor levels of contrast and brightness, mainly
because of inadequate and improper illumination during the image acquisition process. As a …
