% Membaca gambar
img = imread('test.jpg');

% Representasikan gambar RGB dalam rentang [0, 1]
I = double(img) / 255;
R = I(:,:,1);
G = I(:,:,2);
B = I(:,:,3);

% Konversi gambar ke HSV untuk mendapatkan channel Hue dan Saturation
HSV = rgb2hsv(img);  % rgb2hsv secara otomatis mengonversi gambar RGB ke HSV
H = HSV(:,:,1);  % Komponen Hue
S = HSV(:,:,2);  % Komponen Saturation
V = HSV(:,:,3);  % Komponen Value

% Membuat gambar HSV dengan channel Hue, Saturation, dan Value
HSI = zeros(size(img));
HSI(:,:,1) = H;  % Menyimpan Hue
HSI(:,:,2) = S;  % Menyimpan Saturation
HSI(:,:,3) = V;  % Menyimpan Value

% Menampilkan gambar HSV
figure;
imshow(HSV);
title('HSV Image');

% MATLAB program for RGB to HSI image conversion.
    img = imread('test.jpg');
 
% Represent the RGB image in [0 1] range
    I = double(img) / 255;
    R = I(:,:,1);
    G = I(:,:,2);
    B =    I(:,:,3);
 
% Converting the image to HSV to 
% obtain the Hue and Saturation Channels
    HSV = rgb2hsv(img);
    H = HSV(:,:,1);
    S = HSV(:,:,2);
 
% Intensity
    I = sum(I, 3)./3;
 
% Creating the HSL Image
  HSI = zeros(size(img));
  HSI(:,:,1) = H;
  HSI(:,:,2) = S;
  HSI(:,:,3) = I;
  figure,imshow(HSI); title('HSI Image');
