Abstract EN
A novel approach, Multipeak mean based optimized histogram modification framework (MMOHM) is introduced for the purpose of enhancing the contrast as well as preserving essential details for any given gray scale and colour images.
The basic idea of this technique is the calculation of multiple peaks (local maxima) from the original histogram.
The mean value of multiple peaks is computed and the input image’s histogram is segmented into two subhistograms based on this multipeak mean (mmean) value.
Then, a bicriteria optimization problem is formulated and the subhistograms are modified by selecting optimal contrast enhancement parameters.
While formulating the enhancement parameters, particle swarm optimization is employed to find optimal values of them.
Finally, the union of the modified subhistograms produces a contrast enhanced and details preserved output image.
This mechanism enhances the contrast of the input image better than the existing contemporary HE methods.
The performance of the proposed method is well supported by the contrast enhancement quantitative metrics such as discrete entropy, natural image quality evaluator, and absolute mean brightness error.
