Signal smoothing python
WebJan 27, 2024 · So the mean smoothing filter basically takes away the sharp edges of the original signal to make it more flat around the mean. The larger the order (k) is the smoother is the filtered signal. WebIn this case we might prefer some other method of dealing with the data off the edge of the image, for example by assuming the signal is a flipped version of the signal going towards the edge. See the description of the mode argument in the docstring for scipy.ndimage.gaussian_filter for some other options. Download this page as a Python …
