顆粒噪聲 的英文怎麼說
中文拼音 [kēlìzàoshēng]
顆粒噪聲
英文
grain noise-
They are also quite useful in the analysis of noise problems, e. g. that of film grain noise.
它們對分析噪聲問題（例如底片顆粒噪聲）也是很有用的。In this dissertation, we also use morphological opening operation to get rid of particle noise and reduce the effects of the tiny " thorn "
本文還用數學形態學的開運算方法去除了顆粒噪聲，並降低了細小邊緣「突剌」的影響。We made an improvement in overcoming the defects in speech signal adaptive delta modulation ( abbr. adm ), such as slope overloading and grain noise. in this method, numerical sliding average filtering was used for filtering decoding speech signal. experiments and analyses indicate that the method makes waveforms in good agreement between the decoding of adm and the original pulse coding modulation ( abbr. pcm ) signal, and considerably improves, the playback speech quality in naturalness, legibility and under standability
針對語音信號自適應增量調制（ adm ）方式中斜率過載和顆粒噪聲缺點，提出了一種改進方法，它利用滑動平均方法對解碼后的信號進行數字濾波.試驗和分析表明，該方法使解碼后的信號波形與原脈沖編碼調制（ pcm ）波形具有很好的一致性，使再生語音質量在自然度、清晰度和可懂度方面比改進前均有較大提高The paper gets some information about the outlines, velocity, areas, and change of gas films and internal contracts of balls in different sizes by using subtract operation, binary image, fill holes of images, and so on
通過利用差影演算法減少背景噪聲、圖像的二值化處理和填充處理、氣泡特徵分析、氣泡中心坐標的確定等得到兩相流中氣泡、液滴和顆粒的尺寸和運動速度以及氣膜分佈等兩相流重要參數。The denoising results about solids holdup and pressure fluctuation signals of gas - solids cfb riser indicate that wpa denoising method based on fractal theory can efficiently differentiate the noises from the solids holdup signals, and the denoised effect is much better than that by filter method based on the fourier transform
氣固循環流化床提升管的顆粒濃度和壓力波動信號的去噪結果表明，基於分形理論的小波包去噪方法能有效地區分真實信號和噪聲信號，去噪效果優于傳統的傅立葉變換的濾波方法。分享友人
