|
+.SH NAME |
|
+blind-sinc-wave - Apply cardinal sine-wave repetition to gradient |
|
+.SH SYNOPSIS |
|
+.B blind-sinc-wave |
|
+[-e] |
|
+.RI [ theta0-stream ] |
|
+.SH DESCRIPTION |
|
+.B blind-sinc-wave |
|
+reads a video from stdin, applies a filter to |
|
+each channel to it, and prints the result to |
|
+stdout. The filter is designed for applying |
|
+repetition to a gradient, and thus assumes the |
|
+range of visible values is [0, 1]. The applied |
|
+filter creates a cardinal sine-wave. |
|
+.P |
|
+If |
|
+.I theta0-stream |
|
+is specified, it must be a video with only |
|
+one pixel per frame. When applying the sine |
|
+function, it is applied to the sum of the |
|
+pixel it is applied to and the pixel in |
|
+the same frame in |
|
+.IR theta0-stream . |
|
+.SH NOTES |
|
+.BR blind-arithm (1) |
|
+with the |
|
+.B mul |
|
+and |
|
+.B div |
|
+operators can be used to stretch the wave. |
|
+.SH OPTIONS |
|
+.TP |
|
+.B -e |
|
+Apply optimisation that assumes all channels |
|
+are identical. If |
|
+.I theta0-stream |
|
+is specified, the values from its second channel |
|
+(the Y channel) are used for all channels. |
