Feature 0 is the objectness score, features 1–2 are the x and y scales of the box, features 3–4 are the x and y offsets of the box center (relative to the cell coordinate itself), and features 5–24 are the 20 class scores. All this — for the first anchor.

WebThe number of anchor boxes partilly affects the number of detected boxes. The output of YOLOv2 has shape (13, 13, B* (5+C)), where B is the number of anchor boxes and C is the number of classes you're trying to detect. Thus the output has 13*13=169 grid cells. You can think of them as a division of the input image into 13 by 13 cells.
