Gradient-Weighted Feature Back-Projection: A Fast Alternative to Feature Distillation in 3D Gaussian Splatting
Joji Joseph, Bharadwaj Amrutur, Shalabh Bhatnagar
We introduce a training-free method for feature field rendering in Gaussian splatting. Our approach back-projects 2D features into pre-trained 3D Gaussians, using a weighted sum ba…

Gradient-Driven 3D Segmentation and Affordance Transfer in Gaussian Splatting Using 2D Masks
Joji Joseph, Bharadwaj Amrutur, Shalabh Bhatnagar
3D Gaussian Splatting has emerged as a powerful 3D scene representation technique, capturing fine details with high efficiency. In this paper, we introduce a novel voting-based met…
