WebOct 17, 2024 · Usually, In Image Processing, all filters are built using Gaussian Kernel. High Pass is basically subtracting Low Pass filtered image from the original image. You can create the Gaussian Kernel manually or using fspecial. For fast implementation, have a look here - Fast Gaussian Blur. P.S. WebDec 26, 2024 · 1 Answer Sorted by: 6 There are many approximations for the Laplacian Filter (See The Hypermedia Image Processing Reference - Laplacian/Laplacian of Gaussian ): Indeed this is an High Pass Filter (HPF). Namely it will remove (attenuate) low frequencies (Specifically it will remove the DC Value, namely the output image will have mean value of …
