Z3D: Zero-Shot 3D Visual Grounding from Images

Nikita Drozdov, Andrey Lemeshko, Nikita Gavrilov +3

3D visual grounding (3DVG) aims to localize objects in a 3D scene based on natural language queries. In this work, we explore zero-shot 3DVG from multi-view images alone, without r…

Top-Down Beats Bottom-Up in 3D Instance Segmentation

Maksim Kolodiazhnyi, Anna Vorontsova, Anton Konushin +1

Most 3D instance segmentation methods exploit a bottom-up strategy, typically including resource-exhaustive post-processing. For point grouping, bottom-up methods rely on prior ass…
