基于VC++的迭代阈值分割算法在图像处理中的应用

Application of lteration Threshold Segmentation Algorithm in the Image Processing Based on Visual C++

阈值分割算法是把图像的灰度分成不同的等级,用设置灰度门限的方法确定欲分割物体的边界。该方法中阈值的选取是正确分割图像的关键,采用迭代算法,能有效地消除或减少噪声对阈值的影响.本文对迭代算法的实现方法进行了一定的分析,并利用Visual C++程序设计平台,对迭代算法的实现进行了一些探讨。

The threshold segmentation algorithm is applied to classifying the image grayscale in different levels. The boundary of the object to be segmented is detenmined by setting grayscale threshold. Owing to the selection of the threshold is the key of proper image segmentation, the iteration algorithm is taken to eliminate or reduce effectively the influences of noises on the threshold. This paper carries out some analysis on the realizing methods of the iteration algorithm and does some discussion on the realization of the iteration algorithm by use of Visual C＋＋ programming base.
