Comparing multiple images to a single image

I want to compare a single image with multiple images that i have stored in a folder with the name of 1.bmp, 2.bmp,... 45.bmp. I want to compare a single image which i am capturing from the camera with these images from the folder. How do i compare this one image with these multiple images? (I thought of using the for loop but i don't know how to use it with images)

Any help will be appreciated. Thank You

   % code
   % Save all images name in a sequence manner before doing the operation 
   % names for example im1,im2,im3..or 1,2,3...so on
   %Save the folder of images in the current directory
   Image=capture from camera % do this operation
   path_directory='folder_name'; % 'Folder name'
   original_files=dir([path_directory '/*.bmp']); 
   for k=1:length(original_files)
      filename=[path_directory '/' original_files(k).name];
      image_call=imread(filename);
      % Image call is done
      %Now compare Image and Image_call and do rest operation
  end

srcFiles = dir('E:\ibps\img\1\*.bmp'); image_1=length(srcFiles); srcFiles2 = dir('E:\ibps\img\2\*.bmp'); image_2=length(srcFiles2); for i = 1:image_1 aa = strcat('E:\ibps\img\',srcFiles(i).name); a = imread(aa); %first img for j=1:image_2 bb = strcat('E:\ibps\img\',srcFiles2(j).name); b = imread(bb); %second img a = rgb2ind(a,16); b = rgb2ind(b,16); c = corr2(a,b); %finding the correlation if c==1 disp('The images are same') % display else disp('the images are not same') end end end

i have stored some 15 images in one folder and want to compare each image with other and to see that images r same or not,but i am not getting anything just it is showing the name of the file which i saved can you help plz
