Be Aimed at image enhancement characteristics,an improved hybrid frog-jumping algorithm is proposed.Firstly,adaptive threshold selection strategy is used in updating hybrid frog-jumping,and a probability distribution is given to the value of the objective function of each frog in order to increase the chance of gaining better frog.Secondly,the chaotic sequence is randomly produced in the chaotic system,and the chaotic variables are mapped to the scope of optimization variables.Hybrid frog-jumping can traverse the entire interval to get the group optimal position.Finally,the Beta function is used to implement the image enhancement.Simulation results show that this algorithm is effective in image enhancement and can get higher definition images.
