Claims

C1strongest claim

GraphiXS is a new probabilistic framework that considers multiple types of data uncertainty, aiming for a fundamental augmentation of the current 4D Gaussian Splatting paradigm into a probabilistic setting.

C2weakest assumption

That various types of data uncertainty (view sparsity, missing frames, camera asynchronization) can be holistically incorporated under a single graphical model framework that can be instantiated with primitives such as Gaussians or Student's-t.

C3one line summary

GraphiXS is a new probabilistic graphical framework that augments 4D Gaussian Splatting to systematically handle multiple types of data uncertainty such as view sparsity and missing frames.
