yes,sir,if use different image,may be check
such as
im = imresize(I, 0.3, 'bilinear');
detector = mtcnn.Detector("MinSize", 15, "MaxSize", 308, "PyramidScale", 5);
[bboxes, scores, landmarks] = detector.detect(im);
displayIm = insertObjectAnnotation(im, "rectangle", bboxes, scores, "LineWidth", 2);
imshow(displayIm)
hold on
for iFace = 1:numel(scores)
scatter(landmarks(iFace, :, 1), landmarks(iFace, :, 2), 'filled');
end
