Range Limited Bi-Histogram Equalization for image contrast enhancement
Histogram equalization is a popular technique for enhancing image contrast. However, it tends to change the brightness of an image and hence, this technique is not very well suited to be implemented in consumer electronics, where preserving the original brightness is essential to avoid annoying artifacts. This paper proposes a novel extension of bi-histogram equalization referred to as Range Li...
متن کاملIterative Thresholded Bi-Histogram Equalization for Medical Image Enhancement
20 ABSTRACT Enhancement of human vision to get an insight to information content is of vital importance. The traditional histogram equalization methods have been suffering from amplified contrast with the addition of artifacts and a surprising unnatural visibility of the processed images. In order to overcome these drawbacks, this paper proposes interative, mean, and multi-threshold selection c...
متن کاملMinimum mean brightness error bi-histogram equalization in contrast enhancement
Histogram equalization (HE) is widely used for contrast enhancement. However, it tends to change the brightness of an image and hence, not suitable for consumer electronic products, where preserving the original brightness is essential to avoid annoying artifacts. Bi-histogram equalization (BBHE) has been proposed and analyzed mathematically that it can preserve the original brightness to a cer...
متن کاملContrast Enhancement Using Bi-Histogram Equalization With Brightness Preservation
Contrast enhancement is an important factor in the image preprocessing step. One of the widely accepted contrast enhancement method is the histogram equalization. Although histogram equalization achieves comparatively better performance on almost all types of image, global histogram equalization sometimes produces excessive visual deterioration. A new extension of bi-histogram equalization call...
متن کاملImage Inversion and Bi Level Histogram Equalization for Contrast Enhancement
A novel Image Inversion based Two Level Histogram Equalization (IIBLHE) for contrast enhancement is proposed in this paper. In this method, the first level of equalization is carried out in such a way that the image is inversed first and then histogram equalization is applied; again inversed and the second level of equalization is performed by modifying the probability density function of that ...
