摘要

A technique is presented to construct a multiscale representation of planar contours based on the wavelet transform (WT). To generate this wavelet description, a partial 1-D discrete wavelet transform (DWT) is applied to the vertical and horizontal components of a length-parametrized planar curve. This multiscale representation descomposes the curve into different levels of resolution and allows to reconstruct it to a desired degree of aproximation. The results show that typical objects are well represented by a small number of wavelet coefficients allowing for a compact object shape representation. An aplication of this compact representation for matching and tracking purposes is presented and its results are analized.
