例句

1. The experimental results show this method could give better coding efficiency than the traditional DCT image coding.
   实验结果表明该方法的编码效率优于离散余弦变换编码。
2. It is then subject to such mathematical indignities as wavelet decomposition, multi-resolution Fourier analysis, polyphase filtering and discrete cosine transformation.
   接下来它还要经过一些数学处理程序，比如小波分解，多重分辨率傅立叶分析，多相过滤，离散余弦变换等。
