WebThe easiest way to apply a 3×3 mean filter in ImageJ is through the Process ‣ Smooth command. The fact that the shortcut is Shift + S can almost make this too easy, as I find myself accidentally smoothing when I really wanted to save my image. Take care. To apply larger mean filters, the command is Process ‣ Filters ‣ Mean… . WebA Laplacian filter is an edge detector used to compute the second derivatives of an image, measuring the rate at which the first derivatives change. This determines if a change in adjacent pixel values is from an edge or continuous progression. Laplacian filter kernels usually contain negative values in a cross pattern, centered within the array.
