Computer analogue experiments show that the compression ratio obtained improves greatly with combination of DPCM and integral small wave transformation, compared with only using a single method of them; and good signal-to-noise ratio and reconstructed picture will be obtained.
计算机模拟实验表明，DPCM与整数小波变换相结合的方法比仅用其中一种得到的压缩比大大提高，运用SPIHT算法也使压缩性能有了明显提高，并且能够得到良好的信噪比和重构图像。
