Enhance an image

dip_Error dip_Sharpen ( in, out, weight, bc, ps, sigmas, tc, flavour )
See Laplace
This function enhances the high frequencies ("sharpens") of the input image in by subtracting a Laplace filtered version of in from it. The weight parameter determines by which amount the laplace information is subtracted from the original: output = input - weight * laplace( input ) The sigmas are the Gaussian smoothing parameters of the Laplace operation, and determine how strongly the high-frequency noise in in is suppressed.
