Some problems that are easy to be confused and wrong are pointed out when using the Mallat algorithm for image processing. The constraints of using the Mallat algorithm are given. The problem of image compression based on subband coding is studied by Haar and Daubechies wavelet. Three kinds of wavelet compression coding scheme and a simulation experiment based on constraint conditions are given. The simulation results can inspire us to construct an effective image compression coding scheme and correctly apply the Mallat algorithm.
