Wavelet transform is characterized by multi-resolution
which presents Mallat pyramid structure. It coincides well with the way by which people distinguish object from coarse to fineness and from large to tiny. In addition
the wavelet transform also has many advantages
such as reducing image noise
simplifying calculations
and embodying target image characteristic point. This paper highlights a method of target recognition by wavelet transform.
