A wavelet transform system and an inverse wavelet transform system are disclosed that respectively implement a wavelet transform and an inverse wavelet transform. Semi-orthogonal standard wavelets are used as the basic wavelets in the wavelet transform and the inverse wavelet transform. As a result,...http://www.google.com.tw/patents/US6600838?utm_source=gb-gplus-share專利 US6600838 - System and method for performing wavelet and inverse wavelet transformations of digital data using semi-orthogonal wavelets
