基于双界线的O ts u阈值分割法及其快速算法
Otsu thresholding segmentation method based on two boundaries and its fast algorithm
摘要
Abstract
The traditional two-dimensional(2D)Otsu thresholding segmentation algorithm has been restricted in application for long-paying computation and poor anti-noise capacity.In order to overcome these drawbacks,this paper proposed a 2D Otsu method based on two boundaries and its fast algorithm.In new 2D histogram,two boundaries parallel to diagonal decided the width of object and background region,and the segmentation line perpendicular to diagonal decided the value of threshold.The proposed method applied Roberts operator and linear fitting to obtain two boundaries,then utilized modified Otsu algorithm to calculate threshold,finally reprocessed noise areas.Experimental results show that,the proposed method not only has a fast computational speed,but also owns better segmentation quality and anti-noise capacity.Meanwhile,the proposed fast algorithm lowers the computational complexity further,which makes the real-time of proposed method better.关键词
