One of the important techniques in digital image processing is to enhance images. Contrast
enhancement is a method that is used to enhance images for viewing process or for further …

Images were captured, transformed, transferred and broadcasted every second in our daily
life, Processing of digital images were kept on the top priority since digital images occupies …

Abstract: For images with uneven illumination, an adaptive local Gamma correction method
for low-illumination image enhancement is designed. The algorithm uses the modified …

This paper presents a method for contrast enhancement of low light images. The images
captured in dark or during night-time cannot be properly perceived by human eye because …

This paper presents a new, simple and robust image enhancement algorithm for image
analysis by modifying the gamma value of its individual pixels. Considering the fact that …

Various classical enhancement methods may potentially enhance only the darker regions of
an image in presence of illuminating sources. However, they distort and saturate the brighter …

When applying traditional image enhancement algorithm to low illumination images with
uneven illumination distribution, it is easy to produce color distortion and over enhancement …

Image processing plays a vital role in phantasm application. It improves the visibility of poor
images. Different techniques have been anticipated so far to get better image quality. Image …

In this paper, we propose an efficient method to enhance contrast of digital images. Image
contrast enhancement is a pre-processing step that improves efficiency of other image …

Hue preservation is an essential requirement for color image enhancement, but preserving
hue introduces the gamut problem. A fast technique is proposed which can be applied to …
