基于改进蛙跳算法的图像对比度增强方法
Image contrast enhancement method based on improved shuffled frog leaping algo-rithm
摘要
Abstract
To improve poor image contrast, this paper proposes an image enhancement method based on improved Shuf-fled Frog Leaping algorithm(SFL). According to the enhancement rule of traditional piecewise linear transformation, this method first analyzes and improves the basic SFL algorithm. Then a pair of thresholds of the original image is found auto-matically by combining the improved SFL algorithm with 2D Otsu method. Finally, regarding image contrast as the fit-ness function of the improved SFL algorithm, the transformative slopes of the piecewise linear transformation are searched automatically so as to get the enhancement image. Experimental results show that the proposed method not only can effectively better image contrast, but also is superior to some traditional methods, such as histogram equalization method and the enhancement methods based on basic SFL algorithm or artificial fish swarm algorithm.关键词
