LAM3D: Large Image-Point Clouds Alignment Model for 3D Reconstruction from Single Image

NeurIPS 2024poster

Large Reconstruction Models have made significant strides in the realm of automated 3D content generation from single or multiple input images. Despite their success, these models often produce 3D meshes with geometric inaccuracies, stemming from the inherent challenges of deducing 3D shapes solely…

RGB-based Category-level Object Pose Estimation via Decoupled Metric Scale Recovery

ICRA 2024poster

While showing promising results, recent RGB-D camera-based category-level object pose estimation methods have restricted applications due to the heavy reliance on depth sensors. RGB-only methods provide an alternative to this problem yet suffer from inherent scale ambiguity stemming from monocular o…

Learning To Align Sequential Actions in the Wild

CVPR 2022poster

State-of-the-art methods for self-supervised sequential action alignment rely on deep networks that find correspondences across videos in time. They either learn frame-to-frame mapping across sequences, which does not leverage temporal information, or assume monotonic alignment between each video pa…

Geometric and Physical Constraints for Drone-Based Head Plane Crowd Density Estimation

IROS 2019poster

State-of-the-art methods for counting people in crowded scenes rely on deep networks to estimate crowd density in the image plane. While useful for this purpose, this image-plane density has no immediate physical meaning because it is subject to perspective distortion. This is a concern in sequences…
