• Existing pipelines using fixed anchor selection with 8,192 anchors over-allocate computation under strict budgets regardless of scene complexity.limitation 85%
  Evidencepartial

  most pipelines rely on fixed anchor selection such as Farthest Point Sampling (FPS), typically using 8,192 anchors regardless of scene complexity, which over-allocates computation under strict budgets

  Implicationpartial

  Directly stated as problem statement in abstract, though specific to 'most pipelines'
