give code for data augmentation of image database in matlab

main.m
% Load the image database
imageFiles = dir('path/to/image/database/*.jpg'); % replace with the path to your image database
numImages = length(imageFiles);

% Loop through each image in the database
for i = 1:numImages
    % Read the image
    image = imread(fullfile(imageFiles(i).folder, imageFiles(i).name));
    
    % Apply data augmentation operations
    % Example operations:
    
    % 1. Rotate the image
    angle = randi([-10, 10]); % random rotation angle between -10 and 10 degrees
    rotatedImage = imrotate(image, angle, 'bicubic', 'crop');
    
    % 2. Flip the image horizontally
    flipProb = rand; % random probability for flipping (0 or 1)
    if flipProb > 0.5
        flippedImage = flip(image, 2);
    else
        flippedImage = image;
    end
    
    % 3. Add Gaussian noise to the image
    noiseVar = 0.01; % variance of the Gaussian noise
    noisyImage = imnoise(image, 'gaussian', 0, noiseVar);
    
    % Save the augmented images
    % You can modify the filenames and folder path as per your requirements
    imwrite(rotatedImage, sprintf('path/to/save/rotated_%d.jpg', i));
    imwrite(flippedImage, sprintf('path/to/save/flipped_%d.jpg', i));
    imwrite(noisyImage, sprintf('path/to/save/noisy_%d.jpg', i));
