一种检测宽度的线特征提取方法

线特征提取是计算机视觉及图像处理中的低级处理过程,应用广泛。有关的研究大多数关注于线的位置而忽略了线宽。定义了高斯模板作为局部图像区域,考察区域内灰度值的相似性,通过灰度比较函数获得线响应进行线检测,模板半径与检测到的线宽有着密切的联系。实验结果表明该方法有效地提取了线位置及线宽。

A Line Feature Extracting Method of Detecting Line Width

Line feature extracting is a low level procedure which is used widely in computer vision and image processing.Most research about line detection focuses on line position,whereas ignores line width.Line width detector extracts structure and strength features of lines by minimizing a local image area which is of similarity brightness to each individual pixel.A stable and sensible similarity function for brightness comparison is used to obtain the initial line responses.Gaussian weighting mask is defined as th...
