-my code(diagonal noise)-
clc
k=imread('clue.jpg');
k=rgb2gray(k);
k=double(k);
[x,y]=meshgrid(1:512,1:512);
p=1+sin(x+y);
tp=(k/128+p)/4;
imshow(tp)
-my code(Vertical noise)-
clc
k=imread('clue.jpg');
k=rgb2gray(k);
k=double(k);
sig=30/255;
k(:,:) = k(:,:)/255;
for i=1:3:512
y=randn;
k(:,i) = k(:,i) + sig*y;
end
imshow(k)
I want to put these two noises in one image.
What should I do?

How about
imshow((tp+k)/2)
