摘要
目前对图像的阈值选取进行了改进,其中最大类间方差算法是使用最多的方法之一。该文在对该方法进行分析的基础上,采用改进的大津法,结合遗传算法的优点进行全局寻优,提出了一种改进的最大类间方差值的选取算法,能自动进行最大类间方差阈值的更优选取。实验表明,该方法对图像双峰问题有较好的效果,有效地解决了背景色和目标色的交叉现象。
Currently,algorithms have been presented to improve the threshold in image.The threshold segmentation based on maximum algorithm has been using most,in this paper,analysis this method,we employ the improved Ostu,combine with GA,them present an algorithm to obtain the better threshold.It can obtain Ostu's threshold automatically and better.The results show that this method can deal with bimodality problem better,therefore can tackle effectively with the phenomenon when background and foreground are crossing ...
