Memberi Warna Citra Monochrome Menggunakan MatLab

Citra monochrome atau citra biner adalah citra yang hanya mempunyai dua nilai derajat keabuan yaitu hitam dan putih, warna hitam bernilai 1 dan warna putih bernilai 0. Kali ini kita akan memberi warna pada citra monochrome mengunakan Matlab, langsu saja untuk script programnya dapat dilihat dibawah ini...

>>> Script Program

Image = imread('Penguins.jpg'); y = rgb2gray(Image); [p,q,r] = size(y); for i = 1:1:p for j = 1:1:q if (y(i,j)>= 0) && (y(i,j)< 18) x(i,j,1) = 0; x(i,j,2) = 0; x(i,j,3) = 0; elseif (y(i,j)>= 18) && (y(i,j)< 36) x(i,j,1) = 237; x(i,j,2) = 27; x(i,j,3) = 36; elseif (y(i,j)>= 36) && (y(i,j)< 54) x(i,j,1) = 228; x(i,j,2) = 142; x(i,j,3) = 31; elseif (y(i,j)>= 54) && (y(i,j)< 72) x(i,j,1) = 251; x(i,j,2) = 179; x(i,j,3) = 180; elseif (y(i,j)>= 72) && (y(i,j)< 90) x(i,j,1) = 21; x(i,j,2) = 154; x(i,j,3) = 233; elseif (y(i,j)>= 90) && (y(i,j)< 108) x(i,j,1) = 116; x(i,j,2) = 3; x(i,j,3) = 59; elseif (y(i,j)>= 108) && (y(i,j)< 126) x(i,j,1) = 252; x(i,j,2) = 234; x(i,j,3) = 12; elseif (y(i,j)>= 126) && (y(i,j)< 144) x(i,j,1) = 146; x(i,j,2) = 80; x(i,j,3) = 167; elseif (y(i,j)>= 144) && (y(i,j)< 162) x(i,j,1) = 203; x(i,j,2) = 213; x(i,j,3) = 62; elseif (y(i,j)>= 162) && (y(i,j)< 180) x(i,j,1) = 59; x(i,j,2) = 165; x(i,j,3) = 77; elseif (y(i,j)>= 180) && (y(i,j)< 198) x(i,j,1) = 48; x(i,j,2) = 85; x(i,j,3) = 173; elseif (y(i,j)>= 198) && (y(i,j)< 216) x(i,j,1) = 126; x(i,j,2) = 180; x(i,j,3) = 67; elseif (y(i,j)>= 216) && (y(i,j)< 232) x(i,j,1) = 16; x(i,j,2) = 233; x(i,j,3) = 59; elseif (y(i,j)>= 232) && (y(i,j)< 255) x(i,j,1) = 255; x(i,j,2) = 255; x(i,j,3) = 100; end end end x = x/255; figure,imshow(Image),title('Original'); figure, subplot(1,2,1),imshow(y),title('Monochrome'); subplot(1,2,2),imshow(x),title('Color');
