Pengolahan Citra, Grayscale, Blending, Negasi, Histogram

1. Grayscale

>>        citra1 = imread('1.jpg');

>>        imshow (citra1);

>>        citra2 = imread('2.jpg');

>>        j = rgb2gray(citra2);

>>        imshow (j);

>>        figure, imshow(citra1), figure, imshow(j);

2. Blending

>>        rgb=imread('1.jpg');

>>        rgb2=imread('2.jpg');

>>        rgbgray=rgb2gray(rgb);

>>        rgb2gray=rgb2gray(rgb2);

>>        add = imadd(rgbgray,rgb2gray);

>>        w1=0.5;

>>        w2=w1;

>>        imshow(add); title('hasil penggabungan');

Blending 2

>> RGB = imread('1.jpg');

>> RGB2 = imread('2.jpg');

>> w1 = 0.5;

>> w2 = w1;

>> RGBBlend1 = immultiply(RGB,w1);

>> RGBBlend2 = immultiply(RGB2,w2);

>> Blend=RGBBlend1+RGBBlend2;

>> imshow(Blend);

Blending 3

>> RGB = imread('1.jpg');

>> RGB2 = imread('2.jpg');

>> w1 = 0.5;

>> w2 = w1;

>> RGBBlend1 = immultiply(RGB,w1);

>> RGBBlend2 = immultiply(RGB2,w2);

>> Blend2=RGBBlend1+RGB2;

>> imshow(Blend2);

3. Negasi

>>        rgb = imread('1.jpg');

>>        k=200-rgb;

>>        figure, imshow(k);

4. Histogram

>>           citra2 = imread('2.jpg');

>>           k=225-citra2;

>>           j=rgb2gray(citra2);

>>           subplot(2,1,1);

>>           imshow(k);

>>           subplot(2,1,2);

>>           imhist(j),title('histogram negatif');
