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. WebMATLAB High Boost Filter. Applies High Boost Filter to given image. Gaussian filter is used for blurring. High Boost Filtering Process.
