hsv2rgb
2hsv2rgb
Purpose Convert HSV colormap to RGB colormap
Syntax M = hsv2rgb(H)
Description M = hsv2rgb(H) converts a hue-saturation-value (HSV) colormap to a
red-green-blue (RGB) colormap. H is an m-by-3 matrix, where m is the number
of colors in the colormap. The columns of H represent hue, saturation, and
value, respectively. M is an m-by-3 matrix. Its columns are intensities of red,
green, and blue, respectively.

rgb_image = hsv2rgb(hsv_image) converts the HSV image to the equivalent
RGB image. HSV is an m-by-n-by-3 image array whose three planes contain
the hue, saturation, and value components for the image. RGB is returned as
an m-by-n-by-3 image array whose three planes contain the red, green, and
blue components for the image.
Remarks As H(:,1) varies from 0 to 1, the resulting color varies from red through yellow,
green, cyan, blue, and magenta, and returns to red. When H(:,2) is 0, the
colors are unsaturated (i.e., shades of gray). When H(:,2) is 1, the colors are
fully saturated (i.e., they contain no white component). As H(:,3) varies from
0 to 1, the brightness increases.
The MATLAB hsv colormap uses hsv2rgb([hue saturation value]) where
hue is a linear ramp from 0 to 1, and saturation and value are all 1’s.
