基于改进SPIHT算法的SAR图像压缩
SAR image compression based on modified SPIHT
摘要
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.关键词
