中文拼音 [qìpāozàoshēng]
氣泡噪聲
英文
bubble noise-
Experimental study on noise suppressing of underwater bubble screen
水中氣泡幕對噪聲的屏蔽效果研究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 paper also proposed a new method based on dynamic image process for multi - bubble image with complex background. since this method can automatically pick up background bubble, it promotes the bubble image identity efficiency caused by noise brought by unstable or un - uniform light, scrapes on glass surface, bead and other reasons
摘要對于有復雜背景的多氣泡圖像,本文提出了一種基於動態圖像處理的新方法,該方法能自動地提取出背景圖像,一定程度上解決了光源不穩定、光照不均勻、玻璃壁面有劃痕、水珠等原因帶來的噪聲致使氣泡圖像難以識別的問題。
