Hi,
i don’t really know if it is the right category or forum to post this question, but here is the question: i have a set of images with 2D boxes around objects in those images, in some images there are objects behind buildings that have their 2B box drawn, my question is to know how i could recognize if the objects in boxes are either cars or humans (because those  are the two objects with boxes in my images). the coordinates of the 2D boxes of all objects in an image are know, so i can with OpenCV all the boxes easily draw.
online i have found many article, but all these try to detect objects in an image and construct their boxes, but i already have those boxes, i just want to check if the boxes effectively contain a car or a human.
One of the tool i have found is Yolo, but like i said , it start with predicting the bounding box .
thank you for your answer, i know i have wrote too much
