Finding the median of a set of images [message #6143] Wed, 17 April 1996 00:00

Hello all,

Does anyone have an algorithm for finding the median at each pixel
position for a set of equal size 2-D images? Currently the only way
I have to do this is to extract all the values for a given pixel
position into a 1-D array and find the median on that. Doing it
pixel by pixel like this is inefficient in IDL so I am looking for an
*array* based algorithm that would find all the medians in parallel.

Thanks for any insight.
