multi-layer wavelet decomposition的用法和樣例：
例句
- Each detail image is first denoised with ridgelet threshold method, and then decomposed with wavelet.
對細節圖像進(jìn)行脊波閾值去噪處理，然后再進(jìn)行單層小波分解。 - The high frequency signal can be decomposed, and the frequency field can be divided into tinier ones with the emerging of wavelet packets.
摘要小波包的方法能對高頻信號進(jìn)行小波分解，給出了頻域帶更精細的劃分。
