% Image Unsharp Mask function
% usage:
% [output_img] = imgLaplaceSharp ([input_img], laplace_mask, mpl)
% laplace_mask - mask for laplacian filter (edge detect)
% mpl - multiplier for the sharpening effect (usualy 0.05 - 0.4)
% Effect depends on the edge-detecting mask.

function [img_out] = imgLaplaceSharp (img_in, laplace_mask, mpl)

img_crisp = imgFilter(img_in, laplace_mask);
img_out = img_in + mpl * img_crisp;
