Low pass filter scilab

Web20 uur geleden · Low pass filtering (aka smoothing), is employed to remove high spatial frequency noise from a digital image. The low-pass filters usually employ moving window operator which affects one pixel of the image at a time, changing its value by some function of a local region (window) of pixels. The operator moves over the image to affect all the ... Web19 sep. 2024 · We can certainly do some low-pass filtering, but we have to decide where to place the cutoff frequency. When I look at the spectrum of the original signal, I get the impression that the noise makes a dominant contribution starting at about 5 kHz.
