Because of the orthogonal reconstructing method, the quality of reconstructed image can be greatly improved and the progressive image transmission also becomes possible compared to JPEG algorithm.
相对于JPEG算法,该方法使重建图像的质量得到显著提高,同时也使得逐步重建图像成为可能。

Our research has showed that SPIHT performs better than JPEG while the underwater images are coded in low bit rate. SPIHT also has a good progressive transmission characteristic.
