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.
