Aleth-NeRF: Illumination Adaptive NeRF with Concealing Field Assumption

1 code implementation14 Dec 2023 Ziteng Cui, Lin Gu, Xiao Sun, Xianzheng Ma, Yu Qiao, Tatsuya Harada

The standard Neural Radiance Fields (NeRF) paradigm employs a viewer-centered methodology, entangling the aspects of illumination and material reflectance into emission solely from 3D points.

Unifying Image Processing as Visual Prompting Question Answering

no code implementations16 Oct 2023 Yihao Liu, Xiangyu Chen, Xianzheng Ma, Xintao Wang, Jiantao Zhou, Yu Qiao, Chao Dong

To address this issue, we propose a universal model for general image processing that covers image restoration, image enhancement, image feature extraction tasks, etc.

Aleth-NeRF: Low-light Condition View Synthesis with Concealing Fields

1 code implementation10 Mar 2023 Ziteng Cui, Lin Gu, Xiao Sun, Xianzheng Ma, Yu Qiao, Tatsuya Harada

Common capture low-light scenes are challenging for most computer vision techniques, including Neural Radiance Fields (NeRF).

Matching Is Not Enough: A Two-Stage Framework for Category-Agnostic Pose Estimation

1 code implementation CVPR 2023 Min Shi, Zihao Huang, Xianzheng Ma, Xiaowei Hu, Zhiguo Cao

To calibrate the inaccurate matching results, we introduce a two-stage framework, where matched keypoints from the first stage are viewed as similarity-aware position proposals.

Decorate the Newcomers: Visual Domain Prompt for Continual Test Time Adaptation

no code implementations8 Dec 2022 Yulu Gan, Yan Bai, Yihang Lou, Xianzheng Ma, Renrui Zhang, Nian Shi, Lin Luo

Since pseudo labels are noisy and unreliable, these methods suffer from catastrophic forgetting and error accumulation when dealing with dynamic data distributions.

CALIP: Zero-Shot Enhancement of CLIP with Parameter-free Attention

1 code implementation28 Sep 2022 Ziyu Guo, Renrui Zhang, Longtian Qiu, Xianzheng Ma, Xupeng Miao, Xuming He, Bin Cui

Contrastive Language-Image Pre-training (CLIP) has been shown to learn visual representations with great transferability, which achieves promising accuracy for zero-shot classification.

Both Style and Fog Matter: Cumulative Domain Adaptation for Semantic Foggy Scene Understanding

no code implementations CVPR 2022 Xianzheng Ma, Zhixiang Wang, Yacheng Zhan, Yinqiang Zheng, Zheng Wang, Dengxin Dai, Chia-Wen Lin

Unlike previous methods that mainly focus on closing the domain gap caused by fog -- defogging the foggy images or fogging the clear images, we propose to alleviate the domain gap by considering fog influence and style variation simultaneously.
