Median — VapourSynth R72 documentation

# Median

std.Median(vnode clip[, int[] planes=[0, 1, 2]])

  Replaces each pixel with the median of the nine pixels in its 3x3 neighbourhood. In other words, the nine pixels are sorted from lowest to highest, and the middle value is picked.

  clip

    Clip to process. It must have integer sample type and bit depth between 8 and 16, or float sample type and bit depth of 32. If there are any frames with other formats, an error will be returned.

  planes

    Specifies which planes will be processed. Any unprocessed planes will be simply copied.
