Abstract
A new algorithm to recognize a two-dimensional object of arbitrary
shape is presented. The object boundary is first represented by a
one-dimensional signal. This signal is then used to build the wavelet
transform zero-crossing representation of the object. The algorithm is
invariant to translation, rotation and scaling. Experimental results
show that, compared with the use of Fourier descriptors, our algorithm
gives more stable and accurate results
