小波去噪,利用小波系数在相邻尺度上的相关性关系,针对小波系数估计中硬阈值方法和软阈值方法的缺点,
通过对双重量收缩函数得到的阈值乘以一个合适系数进行修定的折衷方法,提出了一种新的小波域局部自适应去噪算法.实验结果表明,该方法既可以去除噪声,又可以较好地保留图像的高频细节特征.(Wavelet denoising using the wavelet coefficients in adjacent scales of the correlation relationship between the estimation of wavelet coefficients for the hard thresholding and soft thresholding shortcomings, through the contraction of the double weight of the threshold function has been multiplied by a suitable coefficient revised compromise, proposed a new wavelet-domain partially adaptive denoising algorithm. The experimental results show that the method can remove noise, also can be used to retain the details of the characteristics of high-frequency images.)

Abstract— We propose a simple speech compression algorithm
using subband division and ADPCM (Adaptive Differential
Pulse Code Modulation) algorithm. Although speech data are
stored in a semiconductor memory device, its capacity and the
available network capacity are limited. Therefore, it is necessary to
compress the data as much as possible. The first is that the
reconstructed datum must be understood correctly. Speech signal is
compressed with a ratio of 1/4 using the proposed subband division
and ADPCM (Adaptive Differential Pulse Code
Modulation) algorithm.

本程序实现不用对数据进行2抽取和2插值的快速小波分解,只需对滤波器进行2插值即 可，所以不要求数据的长度为2的幂次方，共分解了3次，然后进行了重构！！！(This procedure achieved without the data extraction and 2 Fast 2 interpolation wavelet decomposition, only 2 of the interpolation filter that can be, so the data length does not require a power of 2, a total break down three times, then refactored! ! !)
