low - pass method的用法和樣例：
例句
- Experimental study is reported on real time measurement of velocity of solid surfaces by using spacial filtering method.
本文報道了基於空間濾波法對變加速運動物體表面運動速度進行實時測量的實驗研究。 - Simulation experimental results indicate that the method gives better visual quality and PSNR gains than applied wavelet transformation denoising method or HOS filter only.
實驗結果表明，相對於單一的小波變換去噪或高階統計量濾波法去噪，所給方法在視覺和峰值信噪比增益上都取得較好效果。
