For example, there are two anchor boxes to make two predictions per location in the image below. Each anchor box is tiled across the image. The number of network outputs equals the number of tiled anchor boxes. The network produces predictions for all outputs.

YOLO and adjusting number of anchor boxes for custom dataset

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. WebNow, we can draw all the anchor boxes centered on (250, 250) in the image.
