主要介绍了使用harr小波进行图像压缩的原理和方法。通过使用小波变换，实现DC和AC的区分与解交织。-Introduces harr wavelet for image compression theory and methods. By using wavelet transform, to achieve the distinction between DC, and AC mixed with the solution.

Channel Estimation in Wavelet Transform using Harr filter (4-levels)

This Program presents discrete wavelet transform (DWT) and its inverse (IDWT) with Haar wavelets as tools to compute the variable size interpolated versions of an image at optimum computational load. As a human observer moves closer to or farther a s

利用Harr小波对图像进行小波变换，提取一定数量的大系数，然后进行还原。(The image wavelet transform using Harr wavelet coefficients, extract a certain number, and then restore.)
