WebUnsharp masking works in two steps: Get the Laplacian (second derivative) of your image. Take away the Laplacian (or a fraction of it) from the original image. Or, in pseudocode: sharp_image = image - a * Laplacian ( image) image is our original image and a is a number smaller than 1, for instance 0.2. Let’s see this with some actual Python code.
