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.
cmap = rgb2hsv(M) hsv_image = rgb2hsv(rgb_image)
You can give an example if you know one.
