| 摘 要： | Otsu分割算法是阈值分割技术中广泛使用的一类方法,但它不能准确分割对比度较低或变化较大的图像.借助于数学形态学中高帽变换的概念,提出了一种改进的Otsu算法:先用高帽变换对原始图像处理,在处理后的图像上再进行Otsu分割.仿真实验表明,该方法具有较低的算法复杂度,容易实现且能成功分割出Otsu法不能分割的对象,比Ot...

| Abstract: | Otsu segmentation algorithm is used for image threshold segmentation widely, but it can’t segment images with low or variable contrast exactly. By the help of concept of Top-hat transformation in mathematical morphology, a modified Otsu method is proposed, by which the original images are processed with Top-hat transformation firstly and then segmented by Otsu method. The results of simulation experiments show that the method has advantages of low algorithmic complexity , easy realization, and can segment the special images which Otsu can’s deal with effectively. It has more perfect robustness than Otsu |
