function match = calculateMatch(image1, image2)
    % Convert images to grayscale
    grayImage1 = rgb2gray(image1);
    grayImage2 = rgb2gray(image2);
    
    % Compute the sum of absolute differences (SAD) between the two images
    sad = sum(abs(double(grayImage1(:)) - double(grayImage2(:))));
    
    % Compute the match as a percentage of the maximum possible SAD value
    maxSad = size(grayImage1, 1) * size(grayImage1, 2) * 255; % Assuming images are uint8
    match = (maxSad - sad) / maxSad * 100;
