ICount = 7;
JCount = 7;
p=0;
for i=1:ICount
    for j=1:JCount
        filename1=['10' num2str(i) '_' num2str(j) '.jpg'];
        img = imread(filename1); % Example: image file name 101_1.jpg, 101_2.jpg .... 102_1.jpg ...
        p=p+1;
        if ndims(img) == 3;
            img = rgb2gray(img);
        end % colour image
        disp(['extracting features from ' filename1 ' ...']);
        ff{p} = extractFeatures(img); %User defined function, return single row Minutiae features
    end
end
