Image Processing in the Fourier Domain A low-pass filter leaves the low frequencies alone. We expect a low-pass filter to smooth the image. This is good for removing noise, but blurs the image.
DIGITAL IMAGE FILTERING By Fred Weinhaus Traditional (Static Weight) Convolution Page 7 so that h = 1 25!1!1!1!1!1!1!1!1!1!1!1!124!1!1!1!1!1!1!1!1!1!1!1!1 " # $ $ $ $ $ $ % & ' ' ' ' ' ' The result of using this larger filter will be that the low pass filtered image is blurrier than for the 3x3 case and the high pass filtered image wi
Image Filtering in the Frequency Domain - Paul Bourke - Personal Pages Applying a low pass filter in the frequency domain means zeroing all frequency components above a cutoff frequency. This is similar to what one would do in a 1 dimensional case except now the ideal filter is a cylindrical "can" instead of a rectangular pu
