摘要
阈值选择是图像分割的基础,提出了基于三次样条函数的多阈值选取算法,能够应用于图像的多阈值分割。首先对图像的直方图进行三次样条函数拟合,再求出三次样条函数的多个极小值,即图像的阈值。实验结果显示,使用提出提出的方法能较准确地识别出直方图的多个波谷,从而实现对图像的多阈值分割。
Threshold selection is the base of the image segmentation. In this paper,the multi-threshold algorithm based on cubic spline function,which can be applied to image multi-threshold segmentation. Firstly it should fit cubic spline function for image histogram,and then obtain multiple minimum values of cubic spline function,namely image thresholds. The experimental results show that this nethod can exactly and relatively identify multi-trough of histogram,to realze image multi-threshold segmentation.
