摘要
为了提高图像增强的视觉效果,采用混沌蛙跳算法。首先对蛙跳位置进行更新,利用Logistic方程产生混沌序列,把混沌变量映射为青蛙;接着在寻优过程中对停止寻优的青蛙施加扰动,并设置了扰动范围;最后利用非完全Beta函数来实现对输入图像的增强,给出了算法流程。实验仿真得出:本文算法与其他算法相比对增强图像细节表现更加清晰。
In order to improve the effect of image enhancement, the chaotic leapfrog algorithm is used. Firstly, the leap frog＇s location is updated. Chaotic sequence is made with logistic equation and the chaotic is maped to frogs. Then dis turbance is put to the stoping frogs in the process of optimization and the range of disturbance is set up. Finaly, the en hancement of the input images is realized with Beta function. The flow chart is given. Experiments show that the algo rithm is better than the ordinary algorithm.
