A refined method of particle shape representation

Abstract A new method using parametric Fourier descriptors to represent particle shape is discussed. This method is compared with the ( R , θ) method described elsewhere [1]. The problem of profile re-entrance inherent in the ( R , θ) method is solved completely.
