| Abstract: | Based on wavelet transform theory and its characteristics,this paper presented methods of image compression,including loss-less compression and high-fidelity compression methods.This paper also put forward the scheme of big size image-compression.A method to deal with the boundary was further investigated by studying the decomposition and reconstruction of Bi-Orthogonal wavelet transform.The results of the test proved that this method could achieve precise reconstruction of Bi-Orthogonal wavelet transform. |

| Keywords: | Bi-Orthogonal wavelet transform boundary disposal weaken pertinence self-adapted coding of transform region image compression |
