基于Canny算子的医用X光图像边缘检测算法研究

Edge Detection Algorithm’s Research of X-Ray Medical Image Based On Canny Operator

为了进一步加强数字图像处理技术在医学图像领域的应用,提供一种基于Canny算子的医用X光图像边缘检测方法。首先介绍边缘检测算法的理论基础,然后结合Canny算子的实现过程,说明边缘检测的所遵循的基本原则,最后对该算法进行了实验验证。从实验的结果可以看出,这种方法对医用X光图像非常有效,对利用计算机进行图像处理有着重要的现实意义。

In order to strengthen the application of digital image processing technique on medical territory, this article supply a kind of edge detection algorithm based on Canny operator. First introduce the theory base of edge detection algorithm ,then combine the achieving process of Canny operator, point out fundamental rule following by edge detection, finally put on the test certification for the operator. From the result of test we can see, this method is very effective for medical X-ray image, and have important actual sense for using computer to process medical image.
