In this paper, we first discuss the construction method of general integer wavelet, and then use the block DPCM and integer wavelet transform to do quasi-distortionless compression of the remote sensing image. The method can be processed in real time, the hardware is simple and can be processed in parallel. The experimental results show that this method Is an effective remote sensing image compression method.
