no11=imread('no1.jpg');
no22=imread('no2.jpg');
bno1 = rgb2gray(no11);
bno2 = rgb2gray(no22);
subplot(2,2,1); imshow(bno1);
subplot(2,2,2); imshow(bno2);
mag1 = abs(fft2(bno1));
mag2 = abs(fft2(bno2));
phas1 = angle(fft2(bno1));
phas2 = angle(fft2(bno2));
C = imfuse(phas1,mag2);
D = imfuse(phas2,mag1);
A = ifft2(C);
B = ifft2(D);
subplot(2,2,3); imshow(A);
subplot(2,2,4); imshow(B);

this is my code and i tried to get the picture of

but the result is

How should I fix it??

Try imshow(A,[])

Dohyun, I think you could take the image 'pixel magnitude' instead of the 'fourier magnitude' to get the output you want. Also, in my opinion it is important ro rescale() the cofficients prior fusing. Refer the the code below.

no11=rescale(double(imread('no1.jpg')));
no22=rescale(double(imread('no2.jpg')));
bno1 = rgb2gray(no11);
bno2 = rgb2gray(no22);
subplot(2,2,1); imshow(bno1); title('Img1');
subplot(2,2,2); imshow(bno2); title('Img2');
phas1 = rescale(angle(fft2(bno1)));
phas2 = rescale(angle(fft2(bno2)));
C = rescale(double(imfuse(phas1,no22,'blend','Scaling','joint')));
D = rescale(double(imfuse(phas2,no11,'blend','Scaling','joint')));
subplot(2,2,3); imshow(C); title('Img1 magnitude + Img2 phase');
subplot(2,2,4); imshow(D); title('Img2 magnitude + Img1 phase');
