| 摘 要： | O tsu阈值分割法是目前应用较为广泛的分割方法,其原理简单,计算量小,性能稳定。本文基于其类间方差和类内方差两个评价函数,在连续域内利用微积分原理进行了改进推广,实现了两个评价函数公式的统一,进而在满足文中函数的同时也满足了两个评价函数的要求,给出了快速实现算法。最后,通过实例对比证明,该方法自动选取的阈值合理,极大提高了图像分割的运算效率。

| Abstract: | The OTSU threshold segmentation method is one of the image segmentation methods which used extensively for its briefness,small computation and stable performance.Based on its two evaluation functions,between-cluster variance and within-cluster variance,this paper extends the algorithm in mean-field with calculous theory and then realizes the unification of the two evaluation functions,which both meets the requirements of the two functions.And then gives a relative fast realization algorithm.The compared exp... |
