Tian Jin · Journal of China Institute of Communications · 2000
In this paper,firstly we discuss a constructing method of integer Haar wavelet transform Secondly Using subblock DPCM and integer Haar wavelet transform,we have obtained the encoding compressive methods of the information entropy proserved for still images,This method are of following some features:the real time processing of remote sensing images are possible for real time transmission;hardware implement is easy;the algorithm is of parallel structure;Lots of experiments illustrate that our method is an effective compressive encoding method for images
