2 .SH NAME | |
3 blind-temporal-mean - Calculate the mean over all frames in a video for … | |
4 .SH SYNOPSIS | |
5 .B blind-temporal-mean | |

7 .I power-stream | |
8 | -p | |

11 .SH DESCRIPTION | |
12 .B blind-temporal-mean | |
13 reads a video from stdin and calculates the mean | |
14 over all frames for each pixel, and outputs a | |
15 single frame video to stdout with the mean for | |
16 each pixel. | |
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 pixel in the single-frame | |
34 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 pixel in the | |
40 single-frame video | |
41 .IR power-stream . | |
42 .TP | |
43 .B -v | |
44 Calculate the variance. | |
45 .SH REQUIREMENTS | |
46 .B blind-temporal-mean | |
47 requires enough free memory to load two full frames memory. | |
48 A frame requires 32 bytes per pixel it contains. If | |
49 .B -p | |
50 or | |
51 .B -v | |
52 is used, enough free memory to load three full frames | |
53 memory is required. If | |
54 .B -l | |
55 is used, enough free memory to load four full frames | |
56 memory is required. | |
57 .P | |
58 .B blind-temporal-mean | |
59 is optimised for simplicity rather than memory usage. | |
