   % Save all 600 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
   %read the given image-assume given image from 600 image folders, say image1.jpg
   image=imread('image1.jpg'); % do this operation
   gray_image=rgb2gray(image);
   path_directory='folder_name'; % 'Folder name' having 600 images
   original_files=dir([path_directory '/*.jpg']); 
   for k=1:length(original_files)
      filename=[path_directory '/' original_files(k).name];
      image_call=imread(filename);
      image_search=rgb2gray(image_call); 
      sub=imsubtract(image_gray,image_search);
      if sub==0
       disp('Given Image found');
       imshow(image_call);
       break;
     end
  end

Respected Kalyan sir, while reading 600 images automatically, suppose each image has five results to write on excel sheet in row form(not column). i want to save each image result in excel sheet in one row. second image result in second row of same columns and so on. what is its code?

There are some things in Kalyan's answer that I don't like, namely using the built in function name "image" as the name of a variable, and converting to gray scale instead of simply using isequal() to check for a match. I offer my code below:

% Specify the folder where the files live.
myFolder = pwd;   %or 'C:\wherever.....';
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end

% Read in the reference image
refFileName = fullfile(myFolder, 'refimage.jpg');
if ~exist(refFileName, 'file')
  errorMessage = sprintf('Error: The following image does not exist:\n%s', refFileName);
  uiwait(warndlg(errorMessage));
  return;
end
% Load reference image and display it.
referenceImage = imread(refFileName);
subplot(1, 2, 1);
imshow(referenceImage);
title('Reference Image');
subplot(1, 2, 2);  % Switch to right axes.

% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.jpg'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
refImageFound = false;
for k = 1 : length(theFiles)
  baseFileName = theFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  % Display the image.
  thisImage = imread(fullFileName);
  imshow(thisImage);  % Display image.
  title(baseFileName);
  drawnow; % Force display to update immediately.
  if isequal(thisImage, referenceImage)
    refImageFound = true;
    uiwait(helpdlg('Found it!'));
    break;
  end
end
if ~refImageFound
  uiwait(warndlg('Reference image not found!'));
end

Thank you Image Analyst sir, great advice. I will try to incorporate it in my future code.

Thanks again!
