Gaussian Splatting for Real-Time Scene Reconstruction: Methods, Systems, and Trade-offs
Ashim Dahal, Rabab Abdelfattah, Nick Rahimi
3D Gaussian Splatting (3DGS) allows for high-quality real-time novel-view synthesis. Since its inception in 2023, its explicit and highly configurable scene representation has been…

MetaSampling: Making Frame Samplers Efficient for Long-Video Question Answering
Ashim Dahal, Bikramjit Banerjee
Frame selection is an important component of long-video question answering (VQA) with Multimodal Large Language Models (MLLMs). Existing frame-selection methods improve over simple…

Does it matter which Gaussians you pick in 4D Gaussian streaming?
Ashim Dahal, Rabab Abdelfattah, Nick Rahimi
Anchor-driven 4D Gaussian streaming methods such as Instant Gaussian Stream (IGS) update a dynamic scene each frame from a compact set of Gaussian anchors, chosen by default with F…
