SAR image compression based on modified SPIHT

doi:10.7523/j.issn.2095-6134.2012.2.011

Abstract

Abstract:

Wavelet transform and SPIHT has achieved a perfect effect on SAR(synthetic aperture radar) image compression, but the complexity of SPIHT limits the encoding rate. Considesing slow coding rate and large memory consuming of SPIHT, we propose a modified listless SPIHT in order to speed up the coding rate. The experiments show that this new method can achieve the same compression effect as SPIHT while has a far faster rate than the original one. So it is suitable for real-time application.

Key words: synthetic aperture radar (SAR), image compression, embedded coding, listless SPIHT
