About size-aware circle NMS #17

Closed thom966 closed 1 year ago

Hello, thank you for your great work.

I have read the paper and am having hard time understanding size-aware circle NMS. In page 5, it says, "The blue box with a lower score will be suppressed in scenarios like the left portion of Fig 3 because it has a greater _xthre and _ythre. The blue box will be suppressed in scenarios like the right portion of Fig. 3 because the distances in the x and y axes are more likely to be smaller than xthre and ythre in the mean time."

How does the left portion of Fig 3 has greater thredholds and the right portion is smaller than two thresholds?
