An Improved Cuckoo Search based Optimal Ranged Brightness Preserved Histogram Equalization and Contrast Stretching Method

Quraishi, Md. Iqbal; Das, Sanjoy; Dhal, Krishna Gopal - In: International Journal of Swarm Intelligence Research (IJSIR) 8 (2017) 1, pp. 1-29

This paper is organized into two main parts. In the first part, two methods have been discussed to preserve the original brightness of the image which are Parameterized transformation function and a novel variant of modified Histogram Equalization (HE) method. In this study both methods have...

Entropy based Range Optimized Brightness Preserved Histogram-Equalization for Image Contrast Enhancement

Das, Sanjoy; Dhal, Krishna Gopal; Sen, Sankhadip; … - In: International Journal of Computer Vision and Image … 6 (2016) 1, pp. 59-72

In this study the over-enhancement problem of traditional Histogram-Equalization (HE) has been removed to some extent by a variant of HE called Range Optimized Entropy based Bi-Histogram Equalization (ROEBHE). In ROEBHE image histogram has been thresholded into two sub-histograms i.e. histograms...
