I want to obtain the coordinates of the object detected by the detector

In MATLAB, there is a learning of a suspended sign detector (https://jp.mathworks.com/help/vision/ug/train-a-stop-sign-detector.html?lang=en), but this detection Is it possible to acquire the coordinate information of the detected object later? I would like to acquire the center coordinates of the detected pause signs by comparing with the learning of the pause sign detector.

translation of the answer in Japanese:

It is easy to understand by running the example.

Get Started with Cascade Object Detector - MATLAB & Simulink - MathWorks

The detection result is:

 >> bbox
 bbox =
   415   135    35    38

This means the x-coordinate, y-coordinate, width, and height of the bounding box (rectangle) respectively. Is it the result you are looking for?

comment for the answer:

Thank you for your answer. I see that each of them was in a bbox, I understand now. I would like to ask again, is it possible to assign the numbers stored in the bbox to variables separately? Sorry for repeating myself.

Substitute the numbers bbox = 415 135 35 38 for x = 415, y = 135, ... and so on.

comment for the comment above:

 x = bbox(1);
 y = bbox(2);

And so on. It is possible.
