Dynamic PlenOctree for Adaptive Sampling Refinement in Explicit NeRF

no code implementations ICCV 2023 Haotian Bai, Yiqi Lin, Yize Chen, Lin Wang

The explicit neural radiance field (NeRF) has gained considerable interest for its efficient training and fast inference capabilities, making it a promising direction such as virtual reality and gaming.

FMapping: Factorized Efficient Neural Field Mapping for Real-Time Dense RGB SLAM

no code implementations1 Jun 2023 Tongyan Hua, Haotian Bai, Zidong Cao, Lin Wang

We then propose the sliding window sampler to reduce uncertainty by incorporating coherent geometric cues from observed frames during map initialization to enhance convergence.

CompoNeRF: Text-guided Multi-object Compositional NeRF with Editable 3D Scene Layout

no code implementations24 Mar 2023 Haotian Bai, Yuanhuiyi Lyu, Lutao Jiang, Sijia Li, Haonan Lu, Xiaodong Lin, Lin Wang

To tackle the issue of 'guidance collapse' and enhance consistency, we propose a novel framework, dubbed CompoNeRF, by integrating an editable 3D scene layout with object specific and scene-wide guidance mechanisms.

Patch-Mix Transformer for Unsupervised Domain Adaptation: A Game Perspective

1 code implementation CVPR 2023 Jinjing Zhu, Haotian Bai, Lin Wang

We solve this problem from a game theory's perspective with the proposed model dubbed as PMTrans, which bridges source and target domains with an intermediate domain.

Weakly Supervised Object Localization via Transformer with Implicit Spatial Calibration

2 code implementations21 Jul 2022 Haotian Bai, Ruimao Zhang, Jiong Wang, Xiang Wan

Weakly Supervised Object Localization (WSOL), which aims to localize objects by only using image-level labels, has attracted much attention because of its low annotation cost in real applications.

AMOS: A Large-Scale Abdominal Multi-Organ Benchmark for Versatile Medical Image Segmentation

1 code implementation16 Jun 2022 Yuanfeng Ji, Haotian Bai, Jie Yang, Chongjian Ge, Ye Zhu, Ruimao Zhang, Zhen Li, Lingyan Zhang, Wanling Ma, Xiang Wan, Ping Luo

Constraint by the high cost of collecting and labeling 3D medical data, most of the deep learning models to date are driven by datasets with a limited number of organs of interest or samples, which still limits the power of modern deep models and makes it difficult to provide a fully comprehensive and fair estimate of various methods.

Deep Learning for Omnidirectional Vision: A Survey and New Perspectives

1 code implementation21 May 2022 Hao Ai, Zidong Cao, Jinjing Zhu, Haotian Bai, Yucheng Chen, Lin Wang

Omnidirectional image (ODI) data is captured with a 360x180 field-of-view, which is much wider than the pinhole cameras and contains richer spatial information than the conventional planar images.
