WebThe median filter is excellent for denoising an image in the case of salt-and-pepper noise because it does not blur the image, as a mean filter would do. Despite its name, the … WebA value of 0 (the default) centers the filter over the pixel, with positive values shifting the filter to the left, and negative ones to the right. By passing a sequence of origins with length equal to the number of dimensions of the input array, different shifts can be specified along each axis. Returns: median_filterndarray Filtered array.
