Hi,

I am using the simple code line to substract one picture from another as given below.

k=image1-image2;

then I will need to subtract 10 more pictures from image 1 to see the difference.

for example:

k=image1-image2;

k1=image1-image3;

k2=image1-image4;

Is there a way that I can make a loop in which all the Images (2,3,4,5,6,7....) I want will be subtracted from image1.

在 MATLAB Online 中打开

Place all images into a cell array.

for m=2:length(image)
    k{m-1}=image{1}-image{m};
end

First you need to read all the images into the cell array.

for m=1:10
    image{m}=imread(sprintf('image%d.jpg',m));%assuming the names of your files are image1.jpg ...
end
for m=2:length(image)
    k{m-1}=image{1}-image{m};
end

Great that works, and if I want to save them images into a folder what should I do?
