摘要
研究了利用阈值对图像进行分割的一般算法。根据图像的特点,从不同的数学角度对阈值的选取进行了分析,改进了基于图像灰度统计特征的边缘强度分割和逐次逼进的阈值迭代算法,并尝试采用多个阈值进行局部分割的算法。对分割结果的对比分析表明,改进后的算法在分割的完整性和一致性上具有更好的效果。
The general arithmetic of image segmentation is introduced. Because of the difference of images, the methods selecting threshold have different mathematic ways. The arithmetic based on statistical character of gray and iterative theory is improved. In addition, efforts are done in partial segment. The result shows that the improved arithmetic works is better in integrality and consistency of image.
