| Abstract: | This paper is first focused on the discussion about the constructing method of general integer wavelet transform.Then by means of subblock DPCM and integer wavelet transforms,the encoding compressive method of the near lossless image compression is obtained for remote sensing images and tested on the experiments.This method is of the following features:(1)the real time processing of remote sensing images is possible for real time transmission;(2)hardware implementation is easy;(3)the algorithm is of parallel structure;(4)only addition,subtraction and bit shift are involved in the processing.Many experiments help illustrate that this method is an effective compressive encoding approach to remote sensing images. |
| Keywords: | image compression integer wavelet transform lift scheme near lossless compression remote sensing image |
