    Abstract: 在過去幾年中,薄膜液晶螢幕顯示器(TFT-LCD)的需求量遽增。自動偵測LCD面板上的瑕疵(稱為mura)在工業生產上,變成為一個非常重要課題。在本論文中,我們題出一個簡單又快速的LCD面板瑕疵偵測法。它包含有五個步驟:(1)一張LCD面板的影像首先經過高斯濾波平滑。(2)從此平滑後的影像,透過平均方式,計算模擬背景影像。(3)將平滑後的影像與模擬背景影像相減,取得差異影像。(4)將差異影像作對比延展並再執行一次高斯濾波。(5)最後,利用邊緣偵測法,例如Canny方法,即可偵測出瑕疵mura區塊。本論文所提出的瑕疵偵測法,僅用到簡單的算數運算,例如:加法、減法、乘法、還有比較等。它既簡單又快速,非常適用於在LCD面板瑕疵偵測工業自動化。
