     16 .SH DESCRIPTION
     17 .B blind-mean
     18 reads videos from
     19 .I stream-1
     20 and the files specified in all succeeding
     21 arguments, and for each pixel in each frame,
     22 calculates the mean of the videos, and prints
     23 the resulting video to stdout.
     24 .P
     25 Unless otherwise specified, the arithmetic mean
     26 is calculated.
