BDCT has been widely used for International Standard of image compression and achieved effective result. However
there exists blocking-artifact problem in loss decoded image processing. In order to reduce satellite image blocking-artifact
the improved blocking-artifact post-processing algorithm based on DCT post-processing method[4] has been proposed
according to the characteristic of the satellite image. The algorithm can not only reduce the blocking-artifact and improve the image quality
but can also save the post-processing time for DCT blocking-artifact and improve the efficiency. This algorithm is extensively useful.
