Web10 aug. 2024 · The low pass filters preserves the lowest frequencies (that are below a threshold) which means it blurs the edges and removes speckle noise from the image in the spatial domain. The high pass filter preserves high frequencies which means it preserves edges. The ‘dft’ function determines the discrete Fourier transform of an image.
