摘要
提出了一种适合于描述近似圆形物体特征的新方法――半径集和向心角集描述及 其傅立叶描述子，并给出了在数字图像中的计算算法。最后对描述子的使用进行了讨论。
A new method which is suitable to describe the features of similar r ound objects is presented in this paper that is the description of radius set an d centripetal angle set as well as Fourier descriptor. The algorithm used in dig ital image processing is given too. Finally, the use of descriptor is discussion in this paper.
