最大类间方差法在图像处理中的应用

Application of the OTSU Method in Image Processing

图像分割在图像处理中占有重要的地位,分割结果的好坏直接影响图像的后续处理。文章首先介绍了最大类间方差法及其改进算法———基于灰度拉伸的最大类间方差法算法原理和实现,并针对高速公路中的图像特点。在背景差分法的基础上利用上述两种方法对图像进行了分割处理,对两种方法处理的结果进行了比较。

Image segmentation is critical in image processing and its results affect the post-algorithms directly.This paper introduces the OTSU and its improved algorithm first. According to the characteristics of the highway images, the above two methods are used for image segmentation based on background subtraction. And the processing results are compared.
