| Abstract: | Some of the properties of the wavelet bases affect the quality of the image coding when wavelet transform is applied to image compression.The impact which the characteristics of wavelet bases function result in the image coding is analyzed and a new method for selecting biorthogonal wavelet bases for image coding is proposed.The evaluation criteria of wavelet bases and the choice of wavelet bases in wavelet image compression coding are studied through experimentation. |
