Fault diagnosis method based on recursive batch least square filter and its application to helicopter ' s electric rudders 遞推批量最小二乘在直升機電動舵機故障診斷中的應(yīng)用
After studied for several decades , there have appeared several classical edge operators , such as roberts , sobel , laplacian , canny and log . meanwhile , there also have presented several classical algorithms of image restoration , such as inverse filter , wiener filter and constrained least squares filter 經(jīng)過多年的研究,已經(jīng)形成了roberts算子、 sobel算子、 laplacian算子、 canny算子、 log算子等經(jīng)典的邊緣檢測算子以及逆濾波、維納濾波、約束最小二值濾波等經(jīng)典的圖像恢復(fù)方法。
