LaplacianFilter

LaplacianFilter[image, r]
convolves image with a range r Laplacian kernel.

LaplacianFilter[image, {r₁, r₂}]
uses ranges r_i in the vertical and horizontal directions.

LaplacianFilter[data, ...]
applies Laplacian filtering to an array of data.

In LaplacianFilter[data, ...], data can be an array of any rank, and can contain symbolic as well as numerical entries.
