How to input add in file names manually?

I am using the following code to input all images from a folder:

% Specify the folder where the files live.
myFolder = 'C:\Users\user\Desktop\matlab\test';
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isfolder(myFolder)
    errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', myFolder);
    uiwait(warndlg(errorMessage));
    myFolder = uigetdir(); % Ask for a new one.
    if myFolder == 0
         % User clicked Cancel
         return;
    end
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.bmp'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
    baseFileName = theFiles(k).name;
    
    fullFileName = fullfile(theFiles(k).folder, baseFileName);
    imageArray = imread(fullFileName);
end

Now suppose, the image names are img1, img2, img3 and so on. I am running a segmentation algorithm, so I want to compare my segmeted masks (img1,img2,img3...) with the original masks (Like the image below) given in the database. I want to use DICE score for this.

I have the original masks given in the dataset in a different folder('C:\Users\user\Desktop\matlab\masks'). They are named like this, img1_mask, img2_mask, img3_mask and so on for each images. They look like this:

Now, I want to find DICE score for img1 and img1_mask, img2 and img2_mask and so on. How do I do this?

"How to input add in file names manually?"

Why do you want to do this manually? Wouldn't it be easier to just:

• use DIR, FILEPARTS, SPRINTF, and FULLFILE, or
• generate all filenames using SPRINTF and FULLFILE ?

Try this:

% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.bmp'); % Change to whatever pattern you need.
refFolder = 'C:\Users\TawsifMostafiz\Desktop\masks';
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
    % Read in the test mask.
    baseFileName = theFiles(k).name;
    fullFileName = fullfile(theFiles(k).folder, baseFileName);
    testMask = imread(fullFileName);
    % Get the reference mask for this image.
    [~, baseFileNameNoExt, ~] = fileparts(baseFileName);
    refBaseFileName = sprintf('%s_mask.png', baseFileNameNoExt);
    refFullFileName = fullfile(refFolder, refBaseFileName)
    if ~isfile(refFullFileName)
        errorMessage = sprintf('The mask for this image does not exist:\n%s', refFullFileName);
        uiwait(errordlg(errorMessage));
        continue; % Skip analysis of it because mask is missing.
    end
    refMask = imread(refFullFileName);
    % Now compute dice
    diceCoefficient = dice(testMask, refMask)
end

@Image Analyst Thanks!

@Stephen can you please elaborate?

If the masks ( the binary images of segmentations) are in folder C:\Users\TawsifMostafiz\Desktop\masks, I want to do in a way where, when img1.png is taken as input, it will also take input from the following location:

C:\Users\TawsifMostafiz\Desktop\masks\img1_mask.png
