在 MATLAB Online 中打开

srcFiles = dir('C:\Users\LENOVO\Desktop\Genuine\1\*.png');  % the folder in which ur images exists
Features = cell(length(srcFiles),1) ;
Valid_points =cell(length(srcFiles),1) ;
for i = 1 : length(srcFiles)
    filename = strcat('C:\Users\LENOVO\Desktop\Genuine\1\',srcFiles(i).name);
    I1 = rgb2gray(imread(filename));
    points1 = detectSURFFeatures(I1);
    [features1, valid_points1] = extractFeatures(I1, points1);
    Features{i} = features1 ;
    Valid_points{i} = valid_points1 ;
    figure; imshow(I1);hold on;
    plot(valid_points1{i}.selectStrongest(10),'showOrientation',true);
end
Features;
Valid_points;

remove the {i} in the plot or else change valid_points1 to Valid_points
