+[-achvy]
+.I sd-stream
+.SH DESCRIPTION
+.B blind-gauss-blur
+reads a video from stdin and a mask video from
+.IR sd-stream .
+The video is printed to stdout, with all pixels are
+blurred using Gaussian blur with a standard
+deviation calculated for each pixel individually.
+The standard deviation is calculated by multiplying
+the X, Y, or Z value with the alpha value of the
+corresponding pixel and frame in
+.IR sd-stream .
+The X value is used when blurring the X channel,
+and analogously for Y and Z. If the standard
+deviation is 0, the pixel is not blurred.
+.P
+If stdin is longer than
+.IR sd-stream ,
+the remainder or stdin is printed without any changes.
+If stdin is shorter than
+.IR sd-stream ,
+the remainder of
+.I sd-stream
+is ignored but may be partially read.
+.SH OPTIONS

+Blur the chroma only, not the luma.

+Pixels with Manhattan distances exceeding
+.I spread
+shall not affect each other. If
+.RB ' auto '
+is specified, this value is calculated from
+the standard deviation used to blir a pixel.
+If -s is not used, there will not be
+distance limit.
+.TP
+.B -v
+Blur vertically only. Has no affect if -h is also
+specified.
+.TP
+.B -y
+Use the Y value (multiplied by the alpha value) from

+as the standard deviation all channels.

+.SH NAME
+blind-invert-luma - Invert the luminosity of a video
+.SH SYNOPSIS
+.B blind-invert-luma
+[-iw]
+.I mask-stream
+.SH DESCRIPTION
+.B blind-invert-luma
+reads a video from stdin and a mask video from
+.IR mask-stream .
+The video is printed to stdout, with the luminosity
+inverted where, in
+.IR mask-stream ,
+the product of the luminosity and the alpha value is
+1, and unchanged where the product is 0. For other
+products, the result is linearly interpolated or
+linearly extrapolated.

+.IR mask-stream ,
+the remainder or stdin is printed without any changes.
+If stdin is shorter than
+.IR mask-stream ,
+the remainder of

+is ignored but may be partially read.
+.SH OPTIONS
+.TP
+.B -i
+Invert the luminosity in
+.I mask-stream
+before calculating the product of the luminosity and
+the alpha value.
+.TP
+.B -w
+Instead of using CIE Standard Illuminant D65 as the
+whitepoint, use the X and Z from each pixel in
+.I mask-stream
+for the whitepoint.
