Density-aware Haze Image Synthesis by Self-Supervised Content-Style Disentanglement

no code implementations11 Mar 2021 Chi Zhang, Zihang Lin, Liheng Xu, Zongliang Li, Wei Tang, Yuehu Liu, Gaofeng Meng, Le Wang, Li Li

The key procedure of haze image translation through adversarial training lies in the disentanglement between the feature only involved in haze synthesis, i. e. style feature, and the feature representing the invariant semantic content, i. e. content feature.

The Unreasonable Effectiveness of the Class-reversed Sampling in Tail Sample Memorization

no code implementations1 Jan 2021 Benyi Hu, Chi Zhang, Yuehu Liu, Le Wang, Li Liu

Long-tailed visual class recognition poses significant challenges to traditional machine learning and emerging deep networks due to its inherent class imbalance.

PyRetri: A PyTorch-based Library for Unsupervised Image Retrieval by Deep Convolutional Neural Networks

1 code implementation2 May 2020 Benyi Hu, Ren-Jie Song, Xiu-Shen Wei, Yazhou Yao, Xian-Sheng Hua, Yuehu Liu

Despite significant progress of applying deep learning methods to the field of content-based image retrieval, there has not been a software library that covers these methods in a unified manner.

Bimodal Stereo: Joint Shape and Pose Estimation from Color-Depth Image Pair

no code implementations16 May 2019 Chi Zhang, Yuehu Liu, Ying Wu, Qilin Zhang, Le Wang

In the pipeline, the estimated shape is refined by the shape prior from the given depth map under the estimated pose.

Joint haze image synthesis and dehazing with mmd-vae losses

no code implementations15 May 2019 Zongliang Li, Chi Zhang, Gaofeng Meng, Yuehu Liu

Fog and haze are weathers with low visibility which are adversarial to the driving safety of intelligent vehicles equipped with optical sensors like cameras and LiDARs.

Spatio-Temporal Road Scene Reconstruction using Superpixel Markov Random Field

no code implementations24 Nov 2018 Yaochen Li, Yuehu Liu, Jihua Zhu, Shiqi Ma, Zhenning Niu, Rui Guo

The data fidelity term in the MRF's energy function is jointly computed according to the superpixel features of color, texture and location.


Contour Guided Hierarchical Model for Shape Matching

no code implementations ICCV 2015 Yuanqi Su, Yuehu Liu, Bonan Cuan, Nanning Zheng

For the purpose, we divide the shape template into overlapped parts and model the matching through a part-based layered structure that uses the latent variable to constrain parts' deformation.
