Program Pembesar Citra dengan Fungsi

Coding:

function g = perbesar(citra, sy, sx)

f = imread(citra);

[baris, kolom] = size(f);

baris_baru    = baris * sy;

kolom_baru = kolom * sx;

f2 = double(f);

for y=1 : baris_baru

    y2 = ((y-1) / sy) + 1;

    for x=1 : kolom_baru

        x2 = ((x-1) / sx) + 1;

        g(y, x) = f(floor(y2), floor(x2));

    end

end

h = uint8(g);

end  %akhir fungsi

u=imread('c:\image\dani.jpg');

z=perbesar('c:\image\dani.jpg', 0.25, 0.25);

subplot(1,2,1);imshow(u),title('citra masukan')

subplot(1,2,2);imshow(z),title('citra perbesar')
