This paper reviews the NTIRE 2024 low light image enhancement challenge, highlighting the proposed solutions and results.

Towards Image Ambient Lighting Normalization

no code implementations27 Mar 2024 Florin-Alexandru Vasluianu, Tim Seizinger, Zongwei Wu, Rakesh Ranjan, Radu Timofte

However, existing works often simplify this task within the context of shadow removal, limiting the light sources to one and oversimplifying the scene, thus excluding complex self-shadows and restricting surface classes to smooth ones.

Rethinking Few-shot 3D Point Cloud Semantic Segmentation

1 code implementation1 Mar 2024 Zhaochong An, Guolei Sun, Yun Liu, Fayao Liu, Zongwei Wu, Dan Wang, Luc van Gool, Serge Belongie

The former arises from non-uniform point sampling, allowing models to distinguish the density disparities between foreground and background for easier segmentation.

See More Details: Efficient Image Super-Resolution by Experts Mining

no code implementations5 Feb 2024 Eduard Zamfir, Zongwei Wu, Nancy Mehta, Yulun Zhang, Radu Timofte

Subsequently, the model delves into the subtleties of rank choice by leveraging a mixture of low-rank experts.

Single-Model and Any-Modality for Video Object Tracking

1 code implementation27 Nov 2023 Zongwei Wu, Jilai Zheng, Xiangxuan Ren, Florin-Alexandru Vasluianu, Chao Ma, Danda Pani Paudel, Luc van Gool, Radu Timofte

In practice, most existing RGB trackers learn a single set of parameters to use them across datasets and applications.

Temporal-aware Hierarchical Mask Classification for Video Semantic Segmentation

1 code implementation14 Sep 2023 Zhaochong An, Guolei Sun, Zongwei Wu, Hao Tang, Luc van Gool

Modern approaches have proved the huge potential of addressing semantic segmentation as a mask classification task which is widely used in instance-level segmentation.

NPF-200: A Multi-Modal Eye Fixation Dataset and Method for Non-Photorealistic Videos

1 code implementation23 Aug 2023 Ziyu Yang, Sucheng Ren, Zongwei Wu, Nanxuan Zhao, Junle Wang, Jing Qin, Shengfeng He

Non-photorealistic videos are in demand with the wave of the metaverse, but lack of sufficient research studies.

Saliency Detection

Alignment-free HDR Deghosting with Semantics Consistent Transformer

no code implementations ICCV 2023 Steven Tel, Zongwei Wu, Yulun Zhang, Barthélémy Heyrman, Cédric Demonceaux, Radu Timofte, Dominique Ginhac

The spatial attention aims to deal with the intra-image correlation to model the dynamic motion, while the channel attention enables the inter-image intertwining to enhance the semantic consistency across frames.

Object Segmentation by Mining Cross-Modal Semantics

1 code implementation17 May 2023 Zongwei Wu, Jingjing Wang, Zhuyun Zhou, Zhaochong An, Qiuping Jiang, Cédric Demonceaux, Guolei Sun, Radu Timofte

In this paper, we propose a novel approach by mining the Cross-Modal Semantics to guide the fusion and decoding of multimodal features, with the aim of controlling the modal contribution based on relative entropy.

CamDiff: Camouflage Image Augmentation via Diffusion Model

1 code implementation11 Apr 2023 Xue-Jing Luo, Shuo Wang, Zongwei Wu, Christos Sakaridis, Yun Cheng, Deng-Ping Fan, Luc van Gool

Specifically, we leverage the latent diffusion model to synthesize salient objects in camouflaged scenes, while using the zero-shot image classification ability of the Contrastive Language-Image Pre-training (CLIP) model to prevent synthesis failures and ensure the synthesized object aligns with the input prompt.

HiDAnet: RGB-D Salient Object Detection via Hierarchical Depth Awareness

no code implementations18 Jan 2023 Zongwei Wu, Guillaume Allibert, Fabrice Meriaudeau, Chao Ma, Cédric Demonceaux

In this paper, from a new perspective, we propose a novel Hierarchical Depth Awareness network (HiDAnet) for RGB-D saliency detection.

Robust RGB-D Fusion for Saliency Detection

1 code implementation2 Aug 2022 Zongwei Wu, Shriarulmozhivarman Gobichettipalayam, Brahim Tamadazte, Guillaume Allibert, Danda Pani Paudel, Cédric Demonceaux

In this work, we aim for RGB-D saliency detection that is robust to the low-quality depths which primarily appear in two forms: inaccuracy due to noise and the misalignment to RGB.

Depth-Adapted CNNs for RGB-D Semantic Segmentation

no code implementations8 Jun 2022 Zongwei Wu, Guillaume Allibert, Christophe Stolz, Chao Ma, Cédric Demonceaux

Recent RGB-D semantic segmentation has motivated research interest thanks to the accessibility of complementary modalities from the input side.

Depth-Adapted CNN for RGB-D cameras

no code implementations21 Sep 2020 Zongwei Wu, Guillaume Allibert, Christophe Stolz, Cedric Demonceaux

These filters compute the spatial coherence by weighting the photometric information on a fixed neighborhood without taking into account the geometric information.
