本文简单介绍了基于小波变换的图像分解与重构，在此基础上讨论了MATLAB语言环境下 图像压缩和图像融合的基本方法-This article briefly introduce the wavelet-based image decomposition and reconstruction, on the basis of discussion under the MATLAB language environment image compression and image fusion of

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
