SharpDepth: Sharpening Metric Depth Predictions Using Diffusion Distillation

Under Review

We present SharpDepth, a diffusion-based depth model for refining metric depth estimators, e.g., UniDepth, without relying on ground-truth depth data. Our method can recover sharp details in thin structures and improve overall point cloud quality.

Semi-supervised 3D Semantic Scene Completion with 2D Vision Foundation Model Guidance

Semi-supervised 3D Semantic Scene Completion with 2D Vision Foundation Model Guidance

The 39th Annual AAAI Conference on Artificial Intelligence

We propose a semi-supervised framework for 3D semantic occupancy prediction that reduces reliance on costly labeled data by leveraging 2D foundation models, achieving up to 85% of full-supervision performance with only 10% labeled data.
