Abstract	As a state-of-the-art image compression algorithm, SPIHT has wider applications in the compression of multi-spectral images. A typical example is an improvement to SPIHT was used to compress multi-spectral images. Although this improvement decreases the requirement for space and time, and makes SPIHT a more appropriate algorithm for hardware implementation, it still contains a great deal of redundant search, greatly reducing encoding speed. In order to solve this problem, the authors of this paper successively proposed a fast search algorithm and an optimized fast search algorithm, and applied them to the improved SPIHT algorithm for multi-spectral image compression, greatly reducing redundant search and improving coding speed. This new idea can also be applied to 3D-SPIHT, 2D-SPECK and 3D-SPECK to achieve higher encoding speed.
