| Abstract: | When wavelet transform is applied to image compression,some of the properties of the wavelet bases affect the quality of the reconstructed image.How to choice wavelet bases reasonably in this area is not well defined.The impact which orthogonality,smooth,symmetry,vanishing moments of wavelet bases function result in on the image coding is analyzed in this paper.From the angle of the experimentation in the matlab,how to choose wavelet base in image compression is discussed. |

| Keywords: | wavelet base image compression orthogonality symmetry vanishing moments |
