说明：  5/3小波变换的提升算法实现以及对于什么叫做提升的介绍。由于5/3小波是整数小波，因此非常适合于DSP处理，且经过提升，小波变换的复杂度明显降低，将此代码的提升部分移植到DSP上，可以达到实时。
(5/3 wavelet transform algorithm to enhance as well as what is to enhance the introduction. Since the 5/3 integer wavelet wavelet is therefore very suitable for DSP processing, and after upgrading, wavelet transform significantly reduced complexity, the upgrading of part of this code ported to DSP, we can achieve real-time.)
