关键词	SPIHT and NLS (Not List SPIHT) are efficient compression algorithms but the algorithms application is limited by the shortcomings of the poor error resistance and slow compression speed in the aviation and other areas requiring high-speed compression. In this paper the error resilience and the compression speed are improved. The remote sensing images are decomposed by Le Gall5/3 wavelet and wavelet coefficients are indexed scanned and allocated by the means of family blocks. The bit-plane importance is predicted by bitwise OR so the N bit-planes can be encoded at the same time. Compared with the SPIHT algorithm this modified algorithm is easy implemented by hardware and the compression speed is improved. The PSNR of reconstructed images encoded by high-speed SPIHT is slightly lower than SPIHT at rate 1bpp but the speed is 4.5-6 times faster than SPIHT encoding process. The algorithm meets the high speed and reliability requirements of aerial applications. 2011 IEEE.
