description: Sharpen the input stream by enhancing its Laplacian.
The effects adds the Laplacian (as computed by the Laplacian plugin) times the 'Amount' parameter to the input stream.
Uses the 'vanvliet' and 'deriche' functions from the CImg library.

Size (diameter) of the filter kernel, in pixel units (>=0). The standard deviation of the corresponding Gaussian is size/2.4. No filter is applied if size < 1.2.

title: Filter
description:
Bluring filter. The quasi-Gaussian filter should be appropriate in most cases. The Gaussian filter is more isotropic (its impulse response has rotational symmetry), but slower.
