wavelet decomposition的意思|示意

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。

First of all, original image is divided into blocks, each subgraph for integer wavelet decomposition, and then the binary image after scrambling embedding.

首先将原始图像进行分块，逐一对每块子图进行整数小波分解，然后将置乱后的二值图像嵌入到低频系数。

The projective curves along the horizontal and vertical directions were obtained from the character images, and were approximated by using wavelet decomposition.

通过对字符图像水平和垂直两个方向的投影曲线分别进行小波分解，得到投影曲线的近似表示。
