weighted pick up strategy and 'confidence-first'

[DF-W]

In learning about this excellent work, we are concerned that the memory strategy proposed in the paper has not been implemented when dealing with 3D images. May I ask the author why?

If these strategies do not exist when dealing with 3D images, how does the approach presented in this paper differ from SAM2?
