A new mathematical model for contrast enhancement in digital images

The aim of this work is to propose a new mathematical model for optimal contrast enhancement digital image. main idea combine the Divide-and-Conquer strategy, and reaction diffusion enhance contrast, highlight information details image, based on conception Sine-Cosine optimization algorithm. technique suitable method with an efficiency that directly depends choice weights in decomposition subspaces. Methods: paper, algorithm has been used selection considering measure (EME). Results: order evaluate effectiveness proposed algorithm, experimental results are presented which show hybridization robustly effective produces clear high images.
