摘要
图像分割是数字图像处理中的一个重要问题。该方法改进了传统的最大类间方差法(Otsu法),使其可以应用于图像的多阈值分割。提出以双峰法引导来提高Otsu法多阈值分割图像的运算速度和稳定性。对样本图像的分割结果显示,此算法在分割速度和效果上都取得了较好的结果。
Image segmentation is a crucial but difficult problem in digital image processing. This paper makes an attempt to apply the Otsu method to mult-thresholds segmentation. An Otsu＇s multi-threshold algorithm guided by bi-peak method is suggested to improve the speed and stability of the algorithm. Segmentation tests on a sample image shows that the algorithm achieves good performance in both efficiency and quality.
