摘要：
In this paper we use Fourier series (FS) to produce normalized descriptors for shape. These descriptors are invariant under any affine transformation. A motion estimation algorithm using FS capable of estimating general two-dimensional affine motion is also proposed. In the case of parameterized shape we use a pseudo affine arc length to compute FS coefficients. (C) 2002 Elsevier Science B.V. All rights reserved.
