基于Hough变换的圆形物体的检测

Detection of circle based on hough transform

Hough变换在图像处理中占有重要地位,但本身具有存储空间大、计算时间长的缺点。利用圆的几何特性,针对Hough变换的缺点进行改进,并将其应用到图像中存在多个圆的情况。实验表明:该算法能较好地减少存储空间,并降低计算时间,同时,能很好地对图像中多个圆进行检测。

Hough transform takes an important part in the image processing, but it has the disadvantages of massive storage space and long calculational time. The disadvantages of Hough transform are modified by using the geometrical characteristic of circle and it is used in the instance of multi-circles in one image. The experiments show that it can reduce storage space and calculational time, and can well detect multi-circles in one image.
