Abstract：To improve the effect of image enhancement, improved shuffled frog leaping algorithm was proposed.Firstly, frogs were grouped, one was used swarm intelligence algorithm, and another was used adaptive algorithm. Secondly, image pixel was mapped code based on real encoding.Thirdly,leap frog was Trimmed update based on fuzzy set.Finally,mean square error function was as evaluation function, and image adaptive enhancement was achieved based on Beta nonlinear transformation function optimal parameter value. Experimental simulation result show: improved shuffled frog leap algorithm has high contrast for image enhancement, processing time is less, pixel data obtained has high precision.
