基于MATLAB的双正交小波图像压缩的对比-MATLAB-based biorthogonal wavelet image compression of the contrast

基于多速率滤波器组的PR条件，本文研究并提出了LPPRFB中综合滤波器组的类型和长度选择的一般性方法；在深入研究两通道LPPRFB和两通道格形小波滤波器组的关系之后，提出了一类可高速实现的具有二进制系数的格形对称双正交小波设计方法，并完成了实例设计-Multirate filter bank based PR conditions, this paper put forward LPPRFB integrated filter in the type and length of the gene

通过双正交小波对图像进行分解，后去噪并重构出图像，使得图像效果更加清晰-The image is decomposed by biorthogonal wavelet, then the image is denoised and reconstructed
