摘要：
Discrete wavelet transform using Daubechies coefficients is applied to decompose a two-dimensional signal into levels. Examples are given using BMP images of a sheep and a thumbprint. The size of the two-dimensional signal is 2(N) by M. It is shown that it is not necessary for M to be a power of 2. A MATLAB program is written for the computations involved.
