Frankenstein: Generating Semantic-Compositional 3D Scenes in One Tri-Plane

no code implementations24 Mar 2024 Han Yan, Yang Li, Zhennan Wu, Shenzhou Chen, Weixuan Sun, Taizhang Shang, Weizhe Liu, Tian Chen, Xiaqiang Dai, Chao Ma, Hongdong Li, Pan Ji

We present Frankenstein, a diffusion-based framework that can generate semantic-compositional 3D scenes in a single pass.

BlockFusion: Expandable 3D Scene Generation using Latent Tri-plane Extrapolation

no code implementations30 Jan 2024 Zhennan Wu, Yang Li, Han Yan, Taizhang Shang, Weixuan Sun, Senbo Wang, Ruikai Cui, Weizhe Liu, Hiroyuki Sato, Hongdong Li, Pan Ji

A variational auto-encoder is employed to compress the tri-planes into the latent tri-plane space, on which the denoising diffusion process is performed.

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

1 code implementation19 Sep 2023 Jiaxin Wei, Xibin Song, Weizhe Liu, Laurent Kneip, Hongdong Li, Pan Ji

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.

Multi-view Tracking Using Weakly Supervised Human Motion Prediction

1 code implementation19 Oct 2022 Martin Engilberge, Weizhe Liu, Pascal Fua

Multi-view approaches to people-tracking have the potential to better handle occlusions than single-view ones in crowded scenes.

Learning to Align Sequential Actions in the Wild

no code implementations CVPR 2022 Weizhe Liu, Bugra Tekin, Huseyin Coskun, Vibhav Vineet, Pascal Fua, Marc Pollefeys

To this end, we propose an approach to enforce temporal priors on the optimal transport matrix, which leverages temporal consistency, while allowing for variations in the order of actions.

Representation Learning

Leveraging Self-Supervision for Cross-Domain Crowd Counting

1 code implementation CVPR 2022 Weizhe Liu, Nikita Durasov, Pascal Fua

State-of-the-art methods for counting people in crowded scenes rely on deep networks to estimate crowd density.

Crowd Counting

Counting People by Estimating People Flows

1 code implementation1 Dec 2020 Weizhe Liu, Mathieu Salzmann, Pascal Fua

Modern methods for counting people in crowded scenes rely on deep networks to estimate people densities in individual images.

Using Depth for Pixel-Wise Detection of Adversarial Attacks in Crowd Counting

no code implementations26 Nov 2019 Weizhe Liu, Mathieu Salzmann, Pascal Fua

State-of-the-art methods for counting people in crowded scenes rely on deep networks to estimate crowd density.

Crowd Counting Density Estimation

Estimating People Flows to Better Count Them in Crowded Scenes

1 code implementation ECCV 2020 Weizhe Liu, Mathieu Salzmann, Pascal Fua

In this paper, we advocate estimating people flows across image locations between consecutive images and inferring the people densities from these flows instead of directly regressing.

Optical Flow Estimation

Context-Aware Crowd Counting

3 code implementations CVPR 2019 Weizhe Liu, Mathieu Salzmann, Pascal Fua

State-of-the-art methods for counting people in crowded scenes rely on deep networks to estimate crowd density.
