Contrastive Gaussian Clustering: Weakly Supervised 3D Scene Segmentation

no code implementations19 Apr 2024 Myrna C. Silva, Mahtab Dahaghin, Matteo Toso, Alessio Del Bue

Recent works in novel-view synthesis have shown how to model the appearance of a scene via a cloud of 3D Gaussians, and how to generate accurate images from a given viewpoint by projecting on it the Gaussians before $\alpha$ blending their color.

PRAGO: Differentiable Multi-View Pose Optimization From Objectness Detections

no code implementations13 Mar 2024 Matteo Taiana, Matteo Toso, Stuart James, Alessio Del Bue

Robustly estimating camera poses from a set of images is a fundamental task which remains challenging for differentiable methods, especially in the case of small and sparse camera pose graphs.
