Is Underwater Image Enhancement All Object Detectors Need?

1 code implementation30 Nov 2023 Yudong Wang, Jichang Guo, Wanru He, Huan Gao, Huihui Yue, Zenan Zhang, Chongyi Li

Coupled with 7 object detection models retrained using raw underwater images, we employ these 133 models to comprehensively analyze the effect of underwater image enhancement on underwater object detection.

Cross-Domain Correlation Distillation for Unsupervised Domain Adaptation in Nighttime Semantic Segmentation

no code implementations CVPR 2022 Huan Gao, Jichang Guo, Guoli Wang, Qian Zhang

The invariance of illumination or inherent difference between two images is fully explored so as to make up for the lack of labels for nighttime images.

UIEC^2-Net: CNN-based Underwater Image Enhancement Using Two Color Space

1 code implementation12 Mar 2021 Yudong Wang, Jichang Guo, Huan Gao, Huihui Yue

However, almost all of these algorithms employ RGB color space setting, which is insensitive to image properties such as luminance and saturation.

Zero-Reference Deep Curve Estimation for Low-Light Image Enhancement

9 code implementations CVPR 2020 Chunle Guo, Chongyi Li, Jichang Guo, Chen Change Loy, Junhui Hou, Sam Kwong, Runmin Cong

The paper presents a novel method, Zero-Reference Deep Curve Estimation (Zero-DCE), which formulates light enhancement as a task of image-specific curve estimation with a deep network.

Stacked Semantics-Guided Attention Model for Fine-Grained Zero-Shot Learning

1 code implementation NeurIPS 2018 Yunlong Yu, Zhong Ji, Yanwei Fu, Jichang Guo, Yanwei Pang, Zhongfei (Mark) Zhang

Zero-Shot Learning (ZSL) is generally achieved via aligning the semantic relationships between the visual features and the corresponding class semantic descriptions.

Bi-Adversarial Auto-Encoder for Zero-Shot Learning

no code implementations20 Nov 2018 Yunlong Yu, Zhong Ji, Yanwei Pang, Jichang Guo, Zhongfei Zhang, Fei Wu

Existing generative Zero-Shot Learning (ZSL) methods only consider the unidirectional alignment from the class semantics to the visual features while ignoring the alignment from the visual features to the class semantics, which fails to construct the visual-semantic interactions well.

Stacked Semantic-Guided Attention Model for Fine-Grained Zero-Shot Learning

no code implementations21 May 2018 Yunlong Yu, Zhong Ji, Yanwei Fu, Jichang Guo, Yanwei Pang, Zhongfei Zhang

To this end, we propose a novel stacked semantics-guided attention (S2GA) model to obtain semantic relevant features by using individual class semantic features to progressively guide the visual features to generate an attention map for weighting the importance of different local regions.

A Cascaded Convolutional Neural Network for Single Image Dehazing

no code implementations21 Mar 2018 Chongyi Li, Jichang Guo, Fatih Porikli, Huazhu Fu, Yanwei Pang

Different from previous learning-based methods, we propose a flexible cascaded CNN for single hazy image restoration, which considers the medium transmission and global atmospheric light jointly by two task-driven subnetworks.

Zero-Shot Learning via Latent Space Encoding

no code implementations26 Dec 2017 Yunlong Yu, Zhong Ji, Jichang Guo, Zhongfei, Zhang

Instead of requiring a projection function to transfer information across different modalities like most previous work, LSE per- forms the interactions of different modalities via a feature aware latent space, which is learned in an implicit way.

DR-Net: Transmission Steered Single Image Dehazing Network with Weakly Supervised Refinement

no code implementations2 Dec 2017 Chongyi Li, Jichang Guo, Fatih Porikli, Chunle Guo, Huzhu Fu, Xi Li

Despite the recent progress in image dehazing, several problems remain largely unsolved such as robustness for varying scenes, the visual quality of reconstructed images, and effectiveness and flexibility for applications.

Emerging from Water: Underwater Image Color Correction Based on Weakly Supervised Color Transfer

no code implementations19 Oct 2017 Chongyi Li, Jichang Guo, Chunle Guo

Underwater vision suffers from severe effects due to selective attenuation and scattering when light propagates through water.

Semantic Softmax Loss for Zero-Shot Learning

no code implementations22 May 2017 Zhong Ji, Yunxin Sun, Yulong Yu, Jichang Guo, Yanwei Pang

However, the visual features and the class semantic descriptors locate in different structural spaces, a linear or bilinear model can not capture the semantic interactions between different modalities well.

Transductive Zero-Shot Learning with Adaptive Structural Embedding

no code implementations27 Mar 2017 Yunlong Yu, Zhong Ji, Jichang Guo, Yanwei Pang

Two fundamental challenges in it are visual-semantic embedding and domain adaptation in cross-modality learning and unseen class prediction steps, respectively.
