A new research paper titled "Mind the Gap" highlights a significant flaw in the standard evaluation of 3D Gaussian Splatting (3DGS) methods. The paper argues that current evaluation protocols, which hold out every Nth frame, primarily measure near-trajectory interpolation rather than true spatial generalization. Researchers introduced a matched-count protocol to isolate this effect, revealing a substantial interpolation-extrapolation gap of 3-12dB across different representations, including neural radiance fields. This gap is large enough to potentially alter method rankings and suggests that standard holdouts are insufficient for assessing spatial generalization capabilities. AI
