Blur image with the median filter. In a window of size n x n centered at pixel (x,y), compute median pixel value over the window. Optionally, ignore values that are too far from the value at current pixel.

im |
an image |
n |
Size of the median filter. |
threshold |
Threshold used to discard pixels too far from the current pixel value in the median computation. Can be used for edge-preserving smoothing. Default 0 (include all pixels in window). |
