Convert RGB colormap to HSV colormap
cmap = rgb2hsv(M)
converts an RGB colormap,
M, to an HSV colormap,
cmap. Both colormaps are m-by-3 matrices. The elements of both colormaps are in the range 0 to 1.
The columns of the input matrix,
M, represent intensities of red, green, and blue, respectively. The columns of the output matrix,
cmap, represent hue, saturation, and value, respectively.
hsv_image = rgb2hsv(rgb_image)
converts the RGB image to the equivalent HSV image. RGB is an m-by-n-by-3 image array whose three planes contain the red, green, and blue components for the image. HSV is returned as an m-by-n-by-3 image array whose three planes contain the hue, saturation, and value components for the image.
