Web10 de ago. de 2024 · Low pass filters and high pass filters are both frequency filters. 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.
