title: Temporal median image of multiple images
body: <p>Is there any other way to calculate the median image of multiple images, other than calculating the median for each individual pixel using <code>np.median(array)</code>?</p>
  
  <p>I know there's already a <a href="https://stackoverflow.com/questions/8736490/need-temporal-median-filter-using-opencv">question about this</a>, but it is from 3 years ago, maybe anything came up. </p>
