摘要
根据小波变换系数分布的特性 ,提出了基于小波变换的图像无损压缩算法、高保真压缩算法和大尺寸图像压缩的解决方案 ,提出了双正交小波变换的边界处理方法 。
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.
