1. a) PENJUMLAHAN DUA CITRA
a=imread('image1.jpg');b=imresize (a,[256 256]);c=rgb2gray(b); j=imread('image2.jpg');k=imresize (j,[256 256]);l=rgb2gray(k);
x=imadd(c,l);y=uint8(x);subplot(1,1,1),imshow(y),title('citra hasil penjumlahan');
b) PENGURANGAN DENGAN NILAI SKALAR TERTENTU (-100)
a=imread('image1.jpg');b=imresize (a,[256 256]);c=rgb2gray(b); j=imread('image2.jpg');k=imresize (j,[256 256]);l=rgb2gray(k);
x=c-100;y=uint8(x);figure,imshow(y),title('citra 1');
c) PENAMBAHAN DENGAN NILAI SKALAR TERTENTU (+100)
a=imread('image1.jpg');b=imresize (a,[256 256]);c=rgb2gray(b);j=imread('image2.jpg');k=imresize (j,[256 256]);l=rgb2gray(k);x=c+100;y=uint8(x);figure,imshow(y),title('citra 1');
d) PEMBAGIAN DENGAN SKALAR TERTENTU
a=imread('image1.jpg');b=imresize (a,[256 256]);c=rgb2gray(b); j=imread('image2.jpg');k=imresize (j,[256 256]);l=rgb2gray(k);

f) OPERASI BOELAN ( and, or, not)
And
a=imread('image1.jpg');

j=imread('image2.jpg');
k=imresize (j,[256 256]);

j=imread('image2.jpg');
k=imresize (j,[256 256]);
l=rgb2gray(k);
x=bitor(c,l);
figure,imshow(x),title('citra or');
XOR
a=imread('image1.jpg');
b=imresize (a,[256 256]);
c=rgb2gray(b);
j=imread('image2.jpg');
k=imresize (j,[256 256]);
l=rgb2gray(k);
x=bitxor(c,l);
figure,imshow(x),title('citra xor');
2. a) TRANSLASI citra=imresize(citra,[256 256],'bilinear');[baris, kolom, layer]=size(citra);citra=double(citra);for i = 1:barisfor j = 1:kolomfor k = 1:layercitraCerminOrigin(i,j,k)=citra(baris-i+1,kolom-j+1,k);endendendcitraCerminOrigin=uint8(citraCerminOrigin);citra=uint8(citra);subplot(1,2,1),imshow(citra), title('citra asli');subplot(2,2,2),imshow(citraCerminOrigin), title('citra Cermin Origin');
b) ROTASI a=imread('image1.jpg'); b=imrotate(a,60,'bilinear');
c=uint8(b); subplot(1,2,1),imshow(a),title('Citra asli'); subplot(1,2,2),imshow(c),title('Citra setelah dirotasi');
c) SCALING
