I have 12 images in the folder, i have wrritten a code for cropping those images and saving them automatically with the same cropping area if you crop one image.

Problem i am facing is, it is cropping first image only and saving that first cropped image 12 times (because number images are 12) with different image names (Sample3_ 1, Sample3_ 2,....,Sample3_ 12) as i suggested in the code not cropping remaing 11 images. Can anyone please let me know what is wrong with my code or suggest me how can i get it done.

Below is code for reference

numFiles = numel(FileNames); % no of images 12
for m = 1:numFiles
    a = imread(FileNames{m}); 
    if m == 1
      
ROI=imcrop(a);
drawnow;
    end  
filename = sprintf('Sample3_ %d.tiff', m);
     
    
fpath = 'C:\Users\Admin\Documents\MATLAB\DIC Challenge 1.0/EXAMPLE_SAMPLE'
    
fullFileName = fullfile(fpath, filename);  imwrite(ROI, fullFileName)
      
end

Thanks in advance

I don't get notified by a tag. I happened to see this question, but I could easily have missed it.

How exactly did you want to solve the problem that your images are not the same size?

Okay, Images are same size only.

I want to crop all of those images and do some DIC Analysis on them.

Thanks

在 MATLAB Online 中打开

fpath = 'C:\Users\Admin\Documents\MATLAB\DIC Challenge 1.0/EXAMPLE_SAMPLE' ; 
numFiles = numel(FileNames); % no of images 12
for m = 1:numFiles
    a = imread(FileNames{m}); 
    if m == 1
        [ROI,Rect]=imcrop(a);
        drawnow;
        [m,n,p] = size(a) ; 
    else
        % a = imresize(a,[m n]) ;  % in case images are of different size use this
        ROI = imcrop(a,Rect) ; 
    end
filename = sprintf('Sample3_ %d.tiff', m);      
fullFileName = fullfile(fpath, filename);  imwrite(ROI, fullFileName)      
end
