title: Getting median picture from sequence of images with OpenCV
body: <p>I have a sequence of images for which I want to calculate the median image (as to remove moving elements). Intuitively, hard-coding a loop to go through all the pixels would have a gross running time, as well as fairly large memory usage. Is there a way to easily do this in OpenCV? (I'm not interested in averaging, I need to do a median). I'm writing this for Android (using OpenCV4Android) so obviously computing power is limited.</p>
