WebbImage Sharpening - 影像銳化 影像微分 影像的座標系不是連續,x軸座標 0, 1, 2, ..., x-1, x, x+1, ...,遞增 1。 單一變數,一階微分定義 單一變數,二階微分定義 影像可表示為 x, y 軸兩變數的函數,f(x, y)為座標 (x, y) 的 intensity 影像的二階微分定義,為在 f 分別對 x 及 y 進行兩次偏微分,然後加總。 WebbUnsharp masking is a linear image processing technique which sharpens the image. The sharp details are identified as a difference between the original image and its blurred version. These details are then scaled, and added back to the original image: enhanced image = original + amount * (original - blurred)
