Generally for improving contrast in digital images, HE is the method that commonly used but in result it gives unnatural artifacts like intensity saturation, over-enhancement and noise amplification. To overcome these problems there was a need to partition the image histogram, at first image histogram was partitioned into two parts and then different transformation functions were applied on each partition. After that image histogram was partitioned into many partitions and same process was… 

Histogram equalization and noise removal process for enhancement of image

This paper analyses progressive switching median filer (PSMF) and decision-based algorithm (DBA) techniques for image enhancement and test results show good efficiency in removing salt and pepper noise for different noise density level.

High Efficient Algorithm for Colored Image Enhancement Based Upon Dynamic Histogram Stretching

Experimental results demonstrate that the proposed technique provides better contrast image than the conventional enhancement methods in terms of visual looks and image details, and yet it allows low cost hardware realization.

Histogram Interpolation Methods for Image Contrast Enhancement

Three methods for interpolating the sparse histogram obtained by HE are proposed, and utilize the interpolated histograms as the target ones for histogram specification or histogram matching, which transforms the histogram of a given image into the specified target histogram.

Analysis of Sigmoid Function Method And Histogram Equalization for Enhancement Contrast Image

The results of the tests show that the Histogram Equalization algorithm has an execution time that is greater than the time of the ACEBSF method which is 121.315ms, and if the K1 and K2 values are too small, the image quality improvement will fail.

An Updated CLAHE Approach for Image Enhancement with Advanced Wavelets

A hybrid technique has been applied on the image which considers every part of the image and preserves edges too and provides good result in terms of different images i.e. gray scale or RGB color images as compared to traditional techniques.

Image Contrast Enhancement by Interpolated Histogram Specification

The proposed histogram interpolation method fills empty bins in the equalized histogram by using the neighboring non-zero elements, and preserves the shape of original histogram, to avoid the image over-enhancement which frequently occurs in conventional histogram equalization.


Image processing is a system which is utilized to upgrade crude pictures which are gotten from cameras, sensors set on satellites and air make. The Image processing strategies, picture upgrade

Image Enhancement Method in Decompression Based on F-shift Transformation

This paper proposes a method for image enhancement in the process of decompression that can not only combination merits of the spatial domain method and the transform domain method, but also can reduce the process complexity and maintain the compressibility of the original image.

Significance of Enhancement Technique In Segmentation of Image and Signal: A Review of the literature

This study put down the result for various enhancement techniques for improvement in the image and signal enhancement.

Modified Contrast Enhancement Algorithm Using Numerical Integration Simpson’s Method

This paper presents an efficient method to improve the contrast of low contrast images and at the same time provides satisfactory performances in terms of image contrast and sharpness. It is based on



Histogram Equalization Techniques For Image Enhancement

Comparative analysis of different enhancement techniques for contrast enhancement will be carried out on the basis of subjective and objective parameters.

A Comparative Analysis of Histogram Equalization based Techniques for Contrast Enhancement and Brightness Preserving

Histogram Equalization (HE) is a simple and effective image enhancement technique.But, it tends to change the mean brightness of the image to the middle level of the permitted range, and hence is not

Survey of Contrast Enhancement Techniques based on Histogram Equalization

This paper presents a review of new forms of histogram for image contrast enhancement, with the major difference among the methods in this family is the criteria used to divide the input histogram.

A Dynamic Histogram Equalization for Image Contrast Enhancement

A smart contrast enhancement technique that takes control over traditional histogram equalization for appropriate contrast enhancement of images without introducing any severe side affects such as washed out appearance, over-enhancement of some features and noises, checkerboard effects etc.
