anchor free和anchor base优点缺点

Anchor-based detection methods require the manual design of anchor boxes, which can be time-consuming and difficult to optimize. However, they tend to produce more accurate results, especially in cases of extreme scale variation or highly crowded scenes.

On the other hand, anchor-free detection methods do not require anchor boxes and can be more computationally efficient. However, they may struggle with extreme scale variation and crowded scenes.

Ultimately, the choice between anchor-based and anchor-free methods depends on the specific needs and constraints of the task at hand.
