| Abstract: | The author presented the theoretical basis of wavelet transform and the processing of image decomposition and reconstruction, then discussed the method of image compression using the wavelet transform in the Matlab and analyzed how to choose the wavelet base for the aim. From the angle of the engineering and experimentation, the application of image compression based on the wavelet transform has been discussed. The results of Experiment showed that this method had high compression ratio and many advantages. |
