Enhancing gray image contrast is the first step of image preprocessing. A novel filter is
proposed, implemented and tested using various dark and unclear images. It is seen that the …

Dark image enhancement is an essential requirement in image processing domain. As
images are captured in different illumination conditions, it is important to enhance dark …

Image enhancement is a technique used to get a better quality of an image in terms of its
clarity, brightness and to give the human eye comfortable to look at. There are different types …

Principal objective of image enhancement is to process an image so that result is more
suitable than original image for specific application. Digital image enhancement techniques …

Contrast enhancement of dark images with non-uniform illumination is a difficult task, as
these images have both dark and bright regions. Hence, we cannot use many of the widely …

Image enhancement processes an image to increase the visual information of that image.
Image quality can be degraded for several reasons such as lack of operator expertise …

Image plays an important role in this present technological world and leads to progress in
multimedia communication, various research fields related to image processing, etc. Low …

Among the various existing techniques for the enhancement of dark images, it has been
observed that if the images have certain bright area, then it becomes more bright after …

This paper develops a contrast enhancement technique to recover an image within a given
area, from a blurred and darkness specimen, and improve visual quality. The technique …

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 …
