从二进制图像中分割出圆形形状 [英] Segmenting circle-like shapes out of Binary Image

问题描述

我有几个二进制图像，我的任务是分割圆形形状.圆不是完美的圆形，但是它们看起来都像圆.以下是一些示例图片以及我需要的内容:

从上方可以看到，左边的图像是原始图像，右边的图像是我需要做的.圆与其他形状相交，但是我只想要圆，如红色所示.将需要使用假想线闭合圆.在这种情况下，我可以在图像处理中做什么?

解决方案

您可以使用霍夫变换，首先需要的是边缘图像，然后再使用霍夫变换，如本文中所见

I have several binary images and my task is to segment circle-like shape. The circles are not perfect rounded circle, but all of them will look like circle. Here are some example images and what I need:

As you can see from above, the left images are original images, and the right images are what I need to do. The circles intersect with other shapes, but I only want the circle, as indicated in red. The imaginary lines to close the circle will be required. What can I do in this case in Image Processing?

解决方案

You can use hough transform, first you need is the edge image then you use a hough transform like you can see in this papers
