2 .SH NAME | |
3 blind-sinc-wave - Apply cardinal sine-wave repetition to gradient | |
4 .SH SYNOPSIS | |
5 .B blind-sinc-wave | |
6 [-e] | |
7 .RI [ theta0-stream ] | |
8 .SH DESCRIPTION | |
9 .B blind-sinc-wave | |
10 reads a video from stdin, applies a filter to | |
11 each channel to it, and prints the result to | |
12 stdout. The filter is designed for applying | |
13 repetition to a gradient, and thus assumes the | |
14 range of visible values is [0, 1]. The applied | |
15 filter creates a cardinal sine-wave. | |
16 .P | |
17 If | |
18 .I theta0-stream | |
19 is specified, it must be a video with only | |
20 one pixel per frame. When applying the sine | |
21 function, it is applied to the sum of the | |
22 pixel it is applied to and the pixel in | |
23 the same frame in | |
24 .IR theta0-stream . | |
25 .SH NOTES | |
26 .BR blind-arithm (1) | |
27 with the | |
28 .B mul | |
29 and | |
30 .B div | |
31 operators can be used to stretch the wave. | |
32 .SH OPTIONS | |
33 .TP | |
34 .B -e | |
35 Apply optimisation that assumes all channels | |
36 are identical. If | |
37 .I theta0-stream | |
38 is specified, the values from its second channel | |
39 (the Y channel) are used for all channels. | |
