A parametrical description of plane curves using wavelet descriptors

We propose and illustrate the application of wavelet descriptors for the quantitative description of shapes. Fourier descriptors are known to be useful for describing shapes based on their boundaries. As these basically operate at one given scale or resolution, their application leads to loss of information of salient features of a shape contained at other scales. Due to their inherent multiscale properties wavelet descriptors are potentially suitable for shape discrimination in such situations. The basic techniques of applying wavelet descriptors in practical applications are given
