hsv2rgb - Convert a HSV image to the equivalent RGB image.

Calling Sequence

RGB = hsv2rgb(HSV)

Parameters

• HSV: A HSV image (hypermat). The dimension of HSV should be M x N x 3, the type should be double and the element value range should be [0,1].
• RGB: Output image, which has the same size as HSV and type of double.

Description

hsv2rgb convert a HSV image to the equivalent RGB image. The relationship between RGB and HSV described as follows:

V = max(R,G,B)

S = (V-min(R,G,B))/V if V<>0, 0 otherwise

H =

(G - B)/6/S, if V=R;

1/2+(B - R)/6/S, if V=G;

2/3+(R - G)/6/S, if V=B.

Supported classe: DOUBLE.

Examples

    RGB = imread('lena.png');
    HSV = rgb2hsv(RGB);
    RGB = hsv2rgb(HSV);
