单参数Hough变换实现圆检测方法的研究

The research of single parameter hough transformation to detect the image of circularity

Hough变换因其可靠性高而在数字图像处理领域中有广泛的应用,但本身具有存储空间大、计算复杂、处理时间长等缺点。在分析了Hough变换及其多种改进方法之后,利用圆的几何特性,给出了一种新的Hough变换圆检测方法——单参数Hough变换(SPHT)用来实现对圆形图像的检测。

For the nicer reliability, Hough transformation is used very broad in the area of dlgital was put forward, which is called Single Parameter Hough Transformation（SPHT） and used to detect the im- age of circularity.
