小波 [xiǎo bō]
[物] wavelet
small wave
small wave
- 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。
It is then subject to such mathematical indignities as wavelet decomposition, multi-resolution Fourier analysis, polyphase filtering and discrete cosine transformation. - 菲舍尔更喜欢一种比较不常用的数学方法——小波变换，这种方法可以将声音分解成比较短的离散的小波成分。
Fischer prefers to use a less common mathematical process known as the wavelet transformation, which represents the sound in terms of short, discrete components known as wavelets. - 这是上幅图中同样的声音信号形成的声图，但是菲舍尔用了另外一种不同形式的小波进行变换，而且在声图上玩了一些花样，得到了这样花朵锦簇的效果。
This is the same sound as led to the previous image, but Fischer has chosen a different type of wavelet to perform the transform and has played around with the result to produce a floral effect.
