11 .SH DESCRIPTION
12 .B blind-spatial-mean
13 reads a video from stdin and calculates the mean
14 over all pixels for frames, and outputs a
15 video with one pixel in each frame, to stdout with
16 the mean for each frame.
17 .P
18 Unless otherwise specified, the arithmetic mean
19 is calculated.
20 .SH OPTIONS
