|
4 .SH SYNOPSIS |
|
5 .B blind-matrix-transpose |
|
6 [-c] |
|
7 .SH DESCRIPTION |
|
8 .B blind-matrix-transpose |
|
9 creates an affine 2D-transformation matrix for |
|
10 transposition. The parameters for the matrix is read |
|
11 in stdin in format of a blind video, one matrix |
|
12 per frame in stdin created and printed to stdout |
|
13 in format of a blind video. |
|
14 .P |
|
15 Each frame in stdin shall contain exactly 1 pixel, |
|
16 this pixel holds degree of the transposition, 0 |
|
17 meaning no transposition at all, 1 meaning full |
|
18 transposition. |
|
19 .P |
|
20 The luma (encoding in the Y-channel, the second |
|
21 channel) multiplied by the alpha (the fourth channel) |
|
22 of the input pixels are used as the values. Each |
|
23 values in the resulting matrices are stored |
|
24 in all channels. |
|
25 .SH OPTIONS |
|
26 .TP |
|
27 .B -c |
|
28 Create different matrices for each channel. Use |
|
29 values from each channel in stdin to create |
|
30 matrices whose values are stored in the same |
|
31 channels in stdout. |
