NAME
i.rgb.his - Red-green-blue (rgb) to hue-intensity-saturation (his)
raster map color transformation function.
(GRASS Image Processing Program)
SYNOPSIS
i.rgb.his
i.rgb.his help
i.rgb.his
red_input=name
green_input=name
blue_input=name
hue_output=name
intensity_output=name
saturation_output=name
DESCRIPTION
i.rgb.his is an image processing program that
processes three input raster map layers as red, green, and
blue components and produces three output raster map layers
representing the hue, intensity, and saturation of the
data. The output raster map layers are created by a
standard red-green-blue (rgb) to hue-intensity-saturation
(his) color transformation. Each output raster map layer
is given a linear gray scale color table. The current
geographic region definition and mask settings are
respected.
Parameters:
- red_input=name
- Input raster map layer representing the red component.
- green_input=name
- Input raster map layer representing the green component.
- blue_input=name
- Input raster map layer representing the blue component.
- hue_output=name
- Output raster map layer representing hue.
- intensity_output=name
- Output raster map layer representing intensity.
- saturation_output=name
- Output raster map layer representing saturation.
