WebAug 9, 2014 · You'll see that gaussian_filter calls gaussian_filter1d for each axis. In gaussian_filter1d, the width of the filter is determined implicitly by the values of sigma and truncate. In effect, the width w is w = 2*int (truncate*sigma + 0.5) + 1 So (w - 1)/2 = int (truncate*sigma + 0.5) For w = 5, the left side is 2. The right side is 2 if
