Aiming at the compression of remote sensing image,a fast set partitioning in hierarchical tree(SPIHT)algorithm based on the end scan threshold is proposed in this paper.The end scan threshold is used in the encoding process to terminate the scan process when the compression is enough.Experimental results show that the end scan threshold for the different images is the same in the case of the same compression ratio,at the same time it reduces both both the memory reguirement and the time consumption and the qu...
