But how to define the coefficients of the beta function adaptively is still a problem. Applying the differential evolution in image contrast enhancement  we utilize the global quickly search ability of the differential evolution algorithm  adaptive mutation  search  at last searches the optimal  values of beta function and gets an adaptive contrast enhanced image. To avoid trapping into local optimum  a chaotic differential evolution algorithm is proposed. Experimental results show that the proposed algorithm can find the global optimal  in few iterations and save largely computational time and complexity. 2010 IEEE.
