Histogram equalization using a selective filter
The Visual Computer, 2022 AbstractMany popular modern image processing software packages implement a naïve form of histogram equalization. This implementation is known to produce histograms that are not truly uniform. While exact histogram equalization techniques exist, these may produce undesirable artifacts in some scenarios.

Bilateral Histogram Equalization for Contrast Enhancement
International Journal of Software Innovation, 2016 As image enhancement is a well discussed issue, various methods have already been proposed till to date. Some of these methods perform well for specific applications but most of the techniques suffer from artifacts due to the over or under enhancement.

Modified Histogram Segmentation Bi-Histogram Equalization [PDF]
, 2020 In the application of image processing, contrast enhancement is a major step. Conventional methods which are studied in contrast enhancement such as Histogram Equalization (HE) have not satisfactory results on many different low-contrast images and they also cannot automatically handle different images.

Piecewise histogram equalization based image enhancement
Tongxin xuebao, 2011 Piecewise histogram equalization（Piecewise HE） was proposed,which combines the benefits of contrast stretching and existing histogram equalization.The swallow of saturation and brightness is avoided in the enhanced image by a piecewise linear mapping ...

Automatic image equalization and contrast enhancement using Gaussian mixture modeling [PDF]
, 2012 In this paper, we propose an adaptive image equalization algorithm that automatically enhances the contrast in an input image. The algorithm uses the Gaussian mixture model to model the image gray-level distribution, and the intersection points of the ...

Contextual and variational contrast enhancement [PDF]
, 2011 This paper proposes an algorithm which enhances the contrast of an input image using inter-pixel contextual information. The algorithm uses a two-dimensional (2D) histogram of the input image constructed using mutual relationship between each pixel and ...

A Novel Contrast Enhancement Technique on Palm Bone Images
Algorithms, 2014 Contrast enhancement plays a fundamental role in image processing. Many histogram-based techniques are widely used for contrast enhancement of given images, due to their simple function and effectiveness. However, the conventional histogram equalization (
