DA-STC: Domain Adaptive Video Semantic Segmentation via Spatio-Temporal Consistency

1 code implementation22 Nov 2023 Zhe Zhang, Gaochang Wu, Jing Zhang, Chunhua Shen, DaCheng Tao, Tianyou Chai

To solve the challenge, we propose a novel DA-STC method for domain adaptive video semantic segmentation, which incorporates a bidirectional multi-level spatio-temporal fusion module and a category-aware spatio-temporal feature alignment module to facilitate consistent learning for domain-invariant features.

Light Field Reconstruction Using Convolutional Network on EPI and Extended Applications

1 code implementation24 Mar 2021 Gaochang Wu, Yebin Liu, Lu Fang, Qionghai Dai, Tianyou Chai

The main problem in direct reconstruction on the EPI involves an information asymmetry between the spatial and angular dimensions, where the detailed portion in the angular dimensions is damaged by undersampling.

Cross-MPI: Cross-scale Stereo for Image Super-Resolution using Multiplane Images

no code implementations CVPR 2021 Yuemei Zhou, Gaochang Wu, Ying Fu, Kun Li, Yebin Liu

Various combinations of cameras enrich computational photography, among which reference-based superresolution (RefSR) plays a critical role in multiscale imaging systems.

Spatial-Angular Attention Network for Light Field Reconstruction

1 code implementation5 Jul 2020 Gaochang Wu, Yingqian Wang, Yebin Liu, Lu Fang, Tianyou Chai

In this paper, we propose a spatial-angular attention network to perceive correspondences in the light field non-locally, and reconstruction high angular resolution light field in an end-to-end manner.

Light Field Reconstruction Using Deep Convolutional Network on EPI

no code implementations CVPR 2017 Gaochang Wu, Mandan Zhao, Liangyong Wang, Qionghai Dai, Tianyou Chai, Yebin Liu

In this paper, we take advantage of the clear texture structure of the epipolar plane image (EPI) in the light field data and model the problem of light field reconstruction from a sparse set of views as a CNN-based angular detail restoration on EPI.
