Speeding up median calculation

The above line of code calculates the median value of a 1xnx3 array and saves it as a particular point in an image. I was wondering if anyone knows a quicker way to do this, as currently the median function takes up around 7 seconds of the total run time.

staticImage(i,j,:) = round(median(sortedPixels,2));
