	1 .TH BLIND-SINC-WAVE 1 blind
	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.
