How to Add Smaller Anchor Boxes in Object Detection Models

In the given anchor configuration, the last level (P5/32) corresponds to the smallest anchor box size. If you want to have an even smaller anchor box size in the last level, you can add another anchor configuration by adjusting the coordinates of the last level anchors.

For example, you can modify the last anchor configuration to have smaller anchor boxes by reducing the coordinate values. Here's an updated anchor configuration:

• [110,47, 90,90, 133,137] # P6/32
• [80,30, 70,70, 100,100] # P6/64

Now, the last level (P6/64) will have smaller anchor boxes compared to the previous level (P6/32).
