      2 .SH NAME
      3 blind-spatial-mean - Calculate the mean over all pixel for each frame in a video
      4 .SH SYNOPSIS
      5 .B blind-spatial-mean
      6 [-d | -g | -h | -l
      7 .I power-stream
      8 | -p

     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
     21 .TP
     22 .B -d
     23 Calculate the standard deviation.
     24 .TP
     25 .B -g
     26 Calculate the geometric mean.
     27 .TP
     28 .B -h
     29 Calculate the harmonic mean.
     30 .TP
     31 .BR -l \ \fIpower-stream\fP
     32 Calculate the Lehmer mean with the power
     33 specified in the same single-pixel frame
     34 in the video
     35 .IR power-stream .
     36 .TP
     37 .BR -p \ \fIpower-stream\fP
     38 Calculate the power mean (Hölder mean) with
     39 the power specified in the same single-pixel
     40 frame in the video
     41 .IR power-stream .
     42 .TP
     43 .B -v
     44 Calculate the variance.
