Enhancing Information Maximization with Distance-Aware Contrastive Learning for Source-Free Cross-Domain Few-Shot Learning

1 code implementation4 Mar 2024 Huali Xu, Li Liu, Shuaifeng Zhi, Shaojing Fu, Zhuo Su, Ming-Ming Cheng, Yongxiang Liu

For this reason, this paper explores a Source-Free CDFSL (SF-CDFSL) problem, in which CDFSL is addressed through the use of existing pretrained models instead of training a model with source data, avoiding accessing source data.

PlaneRecTR: Unified Query Learning for 3D Plane Recovery from a Single View

1 code implementation ICCV 2023 Jingjia Shi, Shuaifeng Zhi, Kai Xu

3D plane recovery from a single image can usually be divided into several subtasks of plane detection, segmentation, parameter estimation and possibly depth estimation.

ROFusion: Efficient Object Detection using Hybrid Point-wise Radar-Optical Fusion

1 code implementation17 Jul 2023 Liu Liu, Shuaifeng Zhi, Zhenhua Du, Li Liu, Xinyu Zhang, Kai Huo, Weidong Jiang

In this paper, we propose a hybrid point-wise Radar-Optical fusion approach for object detection in autonomous driving scenarios.

Unbiased Scene Graph Generation via Two-stage Causal Modeling

no code implementations11 Jul 2023 Shuzhou Sun, Shuaifeng Zhi, Qing Liao, Janne Heikkilä, Li Liu

To remedy this, we propose Two-stage Causal Modeling (TsCM) for the SGG task, which takes the long-tailed distribution and semantic confusion as confounders to the Structural Causal Model (SCM) and then decouples the causal intervention into two stages.

Deep Learning for Cross-Domain Few-Shot Visual Recognition: A Survey

no code implementations15 Mar 2023 Huali Xu, Shuaifeng Zhi, Shuzhou Sun, Vishal M. Patel, Li Liu

Deep learning has been highly successful in computer vision with large amounts of labeled data, but struggles with limited labeled training data.

SSR-2D: Semantic 3D Scene Reconstruction from 2D Images

no code implementations7 Feb 2023 Junwen Huang, Alexey Artemov, Yujin Chen, Shuaifeng Zhi, Kai Xu, Matthias Nießner

In this work, we explore a central 3D scene modeling task, namely, semantic scene reconstruction without using any 3D annotations.

Cross-Domain Few-Shot Classification via Inter-Source Stylization

no code implementations17 Aug 2022 Huali Xu, Shuaifeng Zhi, Li Liu

The goal of Cross-Domain Few-Shot Classification (CDFSC) is to accurately classify a target dataset with limited labelled data by exploiting the knowledge of a richly labelled auxiliary dataset, despite the differences between the domains of the two datasets.

ILabel: Interactive Neural Scene Labelling

no code implementations29 Nov 2021 Shuaifeng Zhi, Edgar Sucar, Andre Mouton, Iain Haughton, Tristan Laidlow, Andrew J. Davison

ILabel's underlying model is a multilayer perceptron (MLP) trained from scratch in real-time to learn a joint neural scene representation.

In-Place Scene Labelling and Understanding with Implicit Scene Representation

no code implementations ICCV 2021 Shuaifeng Zhi, Tristan Laidlow, Stefan Leutenegger, Andrew J. Davison

Semantic labelling is highly correlated with geometry and radiance reconstruction, as scene entities with similar shape and appearance are more likely to come from similar classes.

SceneCode: Monocular Dense Semantic Reconstruction using Learned Encoded Scene Representations

no code implementations CVPR 2019 Shuaifeng Zhi, Michael Bloesch, Stefan Leutenegger, Andrew J. Davison

Systems which incrementally create 3D semantic maps from image sequences must store and update representations of both geometry and semantic entities.
