Abstract: 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.
