Monocular 3D Object Detection with Bounding Box Denoising in 3D by Perceiver

no code implementations ICCV 2023 Xianpeng Liu, Ce Zheng, Kelvin Cheng, Nan Xue, Guo-Jun Qi, Tianfu Wu

Motivated by a new and strong observation that this challenge can be remedied by a 3D-space local-grid search scheme in an ideal case, we propose a stage-wise approach, which combines the information flow from 2D-to-3D (3D bounding box proposal generation with a single 2D image) and 3D-to-2D (proposal verification by denoising with 3D-to-2D contexts) in a top-down manner.

DiffMesh: A Motion-aware Diffusion-like Framework for Human Mesh Recovery from Videos

no code implementations23 Mar 2023 Ce Zheng, Xianpeng Liu, Mengyuan Liu, Tianfu Wu, Guo-Jun Qi, Chen Chen

While image-based HMR methods have achieved impressive results, they often struggle to recover humans in dynamic scenarios, leading to temporal inconsistencies and non-smooth 3D motion predictions due to the absence of human motion.

Toward Effective Automated Content Analysis via Crowdsourcing

no code implementations12 Jan 2021 Jiele Wu, Chau-Wai Wong, Xinyan Zhao, Xianpeng Liu

For subjective features such as semantic connotation, online workers, known for optimizing their hourly earnings, tend to deteriorate in the quality of their responses as they work longer.
