[Qgis-user] Process images to generate the median

[Eddison Araya]

Hello Kirk thank you very much, maybe my email was not clear, what I want
to calculate is the median (https://en.wikipedia.org/wiki/Median) and not
the average, I do not know if it is clear, but what I want to calculate
it's the median and not the average between the images.

Then how can I calculate an image 6 that represents the median?

Thank you

Eddison
