基于线段扫描的碎纸片边界检测算法研究

提出了基于短线段扫描的碎纸片图像边缘检测算法,该算法用一系列短线段拟合碎纸片的边缘,这些短线段首尾相连,组成碎片边缘拟合曲线;在碎片边界拟合过程中,使用直线插补方法获得线段离散点,通过点的属性来判断线段与碎片边缘的拟合程度,同时使用圆插补方法旋转扫描线段,以保证线段扫描方向连续而没有间断;还分析了碎片图像噪声分布特点,提出了噪声点去除方法;同时提出了多碎片图像边缘检测方法.根据所提出的算法,研制了碎纸片边缘检测程序,并利用这些程序对两实际例子进行了分析,分析结果表明所提出的碎片边缘检测方法是可靠和有效的.

Research on edge detection algorithm for scrapped paper with line segment scanning

This paper investigates an edge detection algorithm for scrapped paper based on line segment scanning.This method fits paper edges with a series of short lines;those short lines link to each other and compose a closed curve of scrapped paper edges.During the progress of edge fitting,line interpolation method is used to obtain discrete points of the short line;the similarity between image edge and short line is estimated through analyzing the point attributes.In order to guarantee the scanning direction cont...
