Hi,
May be that developers already have thought on this question, and may be that it is not easy to implement.
The task is to compute an image as the median of a rather large sequence of images, operating pixel-by-pixel. That is, every resulting pixel should be (in graylevel or luminance or any other 1-dimensional measure) the median of all pixels in the same position along the sequence.
Plase see the discussion in viewtopic.php?f=1&t=17519
Thanks,
José.
