How to use Feature Based Image Registration App for batch of images and export the results. Using the app, I can only register one image at a time. Can I use batch processor to use this Feature Based Image Registration App? If yes, please provide a code based solution

Unfortunately, the Feature Based Image Registration App in MATLAB does not have a built-in batch processing capability. It is designed for interactive use, allowing you to register one image at a time.
However, you can still achieve batch processing by writing a MATLAB script that automates the registration process for a batch of images using the functions provided by the Image Processing Toolbox. Here's an example code-based solution to perform feature-based image registration on a batch of images and export the results:
% Define the folder path containing the input images
inputFolder = 'path_to_input_folder';
% Define the folder path to save the registered images
outputFolder = 'path_to_output_folder';
% Get a list of all image files in the input folder
fileList = dir(fullfile(inputFolder, '*.jpg')); % Update the file extension if needed
% Loop through each image file
for i = 1:numel(fileList)
% Read the current image
imagePath = fullfile(inputFolder, fileList(i).name);
image = imread(imagePath);
% Perform feature-based image registration
% Replace the registration code with your own implementation
% Assuming you have a function called 'registerImages' that performs the registration
registeredImage = registerImages(image);
% Save the registered image to the output folder
[~, imageName, imageExt] = fileparts(fileList(i).name);
outputFilePath = fullfile(outputFolder, [imageName, '_registered', imageExt]);
imwrite(registeredImage, outputFilePath);
end
In this example, you need to specify the `inputFolder` as the path to the folder containing your input images. The script uses `dir` function to get a list of all image files in the folder.
Inside the loop, you can perform the feature-based image registration using your own implementation or any of the registration functions provided by the Image Processing Toolbox, such as `imregister` or `imregtform`.
After registering the image, the script saves the registered image to the `outputFolder` with a modified filename, indicating that it has been registered.
Make sure to update the file extension and the registration code in the script according to your specific requirements.
By running this script, you can automate the feature-based image registration process for a batch of images and export the registered images to the specified output folder.
Hope it helps!
