Semantic Flow: Learning Semantic Field of Dynamic Scenes from Monocular Videos

1 code implementation8 Apr 2024 Fengrui Tian, Yueqi Duan, Angtian Wang, Jianfei Guo, Shaoyi Du

As there is 2D-to-3D ambiguity problem in the viewing direction when extracting 3D flow features from 2D video frames, we consider the volume densities as opacity priors that describe the contributions of flow features to the semantics on the frames.

Learning a Category-level Object Pose Estimator without Pose Annotations

no code implementations8 Apr 2024 Fengrui Tian, Yaoyao Liu, Adam Kortylewski, Yueqi Duan, Shaoyi Du, Alan Yuille, Angtian Wang

Instead of using manually annotated images, we leverage diffusion models (e. g., Zero-1-to-3) to generate a set of images under controlled pose differences and propose to learn our object pose estimator with those images.

Multi-Modal Deep Learning for Credit Rating Prediction Using Text and Numerical Data Streams

1 code implementation21 Apr 2023 Mahsa Tavakoli, Rohitash Chandra, Fengrui Tian, Cristián Bravo

In this paper, we present an analysis of the most effective architectures for the fusion of deep learning models for the prediction of company credit rating classes, by using structured and unstructured datasets of different types.

MonoNeRF: Learning a Generalizable Dynamic Radiance Field from Monocular Videos

1 code implementation ICCV 2023 Fengrui Tian, Shaoyi Du, Yueqi Duan

More specifically, we learn an implicit velocity field to estimate point trajectory from temporal features with Neural ODE, which is followed by a flow-based feature aggregation module to obtain spatial features along the point trajectory.
