Hi Everybody,

I have a list of images for 3 years every two images represent a year. How can I for loop to merge two images (B3 and B4) for each year? All images have the same size

The list of images:

IQ_38_2000_B3

IQ_38_2000_B4

IQ_38_2001_B3

IQ_38_2001_B4

IQ_38_2002_B3

IQ_38_2002_B4

then the output should be like:

IQ_38_2000_Mereged

IQ_38_2001_Mereged

IQ_38_2002_Mereged

Please do reply

Thank you in advance

在 MATLAB Online 中打开

Assuming all your images are '****.png' with the same size and stored in the current folder, the following script can do it.

for kk = 2000:2002
  prefix = ['IQ_38_',num2str(kk)];
  I1 = imread([prefix,'_B3.png']);
  I2 = imread([prefix,'_B4.png']);
  Imerged = [I1,I2];
  imwrite(Imerged,[prefix,'_Merged.png']);
end
