Low-pass filtering is easy and always works fine (not included here). High-pass filtering needs conversion of numbers from integer to float before processing and then conversion back to integer -- to keep numbers within their limits. Lena.jpg example is included. Presented on EAEEIE2010 conference ("Re-inventing Image Processing teaching") and published in a book MATLAB and Simulink by Bogumila & Zbigniew MROZEK, https://helion.pl/ksiazki/matsi4
