All confines of gray scale are segmented into some parts, and multiple threshold is derived through in each part histogram of gradient, concavity analysis of histogram, moment and entropy of histogram. The multiple threshold image segmentation is achieved.
在基于阈值选取的图像分割方法中,本文改进了传统的迭代阈值法和基于梯度、凹度分析、矩、熵的单阈值分割方法,将灰度范围进行了划分,并根据各灰度区间的梯度直方图、直方图的凹度分析,直方图的矩、熵得到多个阈值,实现了图像的多区域分割。
