I've tried the code given in the documentation as below.
It work. Then I try to change the testing image with this image (attachment). But the code only detect one stop sign as the result attachment.
I've tried to comment one line in the code that display only the stongest score. But it still detect one stop sign. supposedly there are 3 stop sign that can be found in the image.
% Display strongest detection result.
[score, idx] = max(score);
How can I improve the code to make it able to detect multiple stop sign?

yes,sir,please use
[bboxes,scores] = detect(detector,I,'Threshold',0.1);
to get more rects,and then filter by score value

yes,sir,it exist wrong detect result by rcnn,may be use faster rcnn or yolo to detect
