Description: 采用离散小波变换方法(Mallat算法)，实现对语音信号的双通道子带压缩编码。将语音信号中，C125Hz的低频区信号完全保留，在125Hz飞KHz频段的语音信号用小波分解逐级进行较为精确的量化并进行滤波，而将高频部分采用游程编，进而达到在保证语音信号原有特性的前提下大幅度的压缩语音信号的传输数据量-The use of discrete wavelet transform method (Mallat algorithm), to realize the dual-channel voice signal sub-band coding. Voice signal, C125Hz low-frequency signals completely retained in the 125Hz band fly KHz voice signal using wavelet decomposition level for more precise quantification and filtering, while the use of high-frequency part of Run-made, thus ensuring the voice signal under the premise of the original characteristics of a substantial compression of voice signals to transmit data volume of

[Graph program] DWT_shuiyin

Description: 提出了一个新的基于量化抖动和模式分组编码的盲数字图像水印算法,该算法首先在DWT(离散小波变换)的第二层中频子带中随机选取相应位置的绝对值最大的系数作为水印的嵌入区间,对小波系数进行量化并根据分组编码原理生成预嵌入模式,然后将一个二值水印图像嵌入到模式当中。-Proposed a new model based on quantitative jitter and packet-coded blind digital image watermarking algorithm, the algorithm first DWT (Discrete Wavelet Transform) and second layer of randomly selected sub-band IF the corresponding absolute value of the location of the largest coefficient watermark embedded interval, the wavelet coefficients to quantify and in accordance with principles of generating the pre-embedded block coding mode, and then a binary watermark image embedded in them patterns.

[Voice Compress] sub-band-coding

Description: 子带编码是一种以信号频谱为依据的波形编码方法，首先用一组带通滤波器将输入信号按频谱分开，然后让每路子信号通过各自的自适应PCM编码器（ADPCM）编码，经过分接和解码再复合成原始信号。-In sub-band coding is a waveform signal based on the spectrum coding method using a first set of band pass filters to separate an input signal spectrum, and so that each signal path through the respective adaptive PCM coder (ADPCM) encoding, after tap and then combined into the original decoding signal.
