因此，提出了一种基于小波变换的因特网图像传输方案，能大大缩短通过因特网的图像传输时间。
Therefore, a lossy Internet image transmission scheme based on wavelet transform is presented, by which Internet image transmission time can be decreased substantially.
最后，进行小波逆变换，得到含有水印信息的虚拟图像，根据虚拟图像中的象素值就可以得到一组新的控制顶点坐标。
Finally, the marked virtual images are gotten with inverse wavelet transform and a new group of control points is obtained based on the pixel value of the virtual image.
并指出基于小波变换的SPIHT编码算法具有对水下图像低比特率编码性能好、可以与纠错技术结合使用等特点。
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.
