基于小波变换的子带编码

matlab小波工具箱，含基本小波变换，与各参考书上对应-matlab wavelet toolbox, containing the basic wavelet transform, with the corresponding reference

大学期间学数字信号处理课程时写的作业放上来也许对大家有用，里面有FIR IIR，和傅立叶变换，FFT等功能。-I uploaded my project report (written by VC) for the module of signal processing when studied in Univ., The functions on FIR IIR and Fourier Transform etc. have been implemented in it. Hope it is benefit for you.

经典的小波变换程序-classic wavelet transform procedures

给出了在matlab环境下的源代码，经过了上机调试，可以实现小波变换对图像的二次压缩！-given Matlab environment in the source code, after the Machine, can achieve a wavelet transform of the second image compression!

CurveLab 图象处理matlab工具箱，对信噪比较低情况下的边界处理有较好的处理效果-CurveLab Image Processing Toolbox Matlab, right lower signal-to-noise ratio of the border is better treatment effect

图像小波变换，可实现1，2，3层小波，图像增强，融合等，功能相当强大-Image wavelet transform, can be realized 1,2,3 layer wavelet, image enhancement, integration, functions quite powerful

it is a function of wavelet transform

由于小波变换具有良好的时频分析特性，已经广泛应用于各种信号分析领域。由于小波变换算法的复杂性，如果直接计算小波变换，所需内存较大，耗时较长。尽管当今处理器芯片运算速度得到了大幅度的提高，但仍然在实时性上不能满足要求。为了简化计算过程，人们相继设计了一系列的快速算法来计算小波变换，以降低其运算次数。-Since the wavelet transform has good time-frequency analysis features, has been widely used in various fields of signal analysis. Wavelet transform algorithm as a result of the complexity, if the direct calculation of wavelet transform, the larger memory requirements, a longer time-consuming. Despite the computational speed of today
