VTP: Volumetric Transformer for Multi-view Multi-person 3D Pose Estimation

no code implementations25 May 2022 Yuxing Chen, Renshu Gu, Ouhan Huang, Gangyong Jia

The proposed VTP framework integrates the high performance of the transformer with volumetric representations, which can be used as a good alternative to the convolutional backbones.

Self-supervised Remote Sensing Images Change Detection at Pixel-level

no code implementations18 May 2021 Yuxing Chen, Lorenzo Bruzzone

To overcome the effects of regular seasonal changes in binary change maps, we also used an uncertainty method to enhance the temporal robustness of the proposed approach.

Self-supervised Change Detection in Multi-view Remote Sensing Images

1 code implementation10 Mar 2021 Yuxing Chen, Lorenzo Bruzzone

In this approach, a pseudo-Siamese network is trained to regress the output between its two branches pre-trained in a contrastive way on a large dataset of multi-temporal homogeneous or heterogeneous image patches.

Self-supervised SAR-optical Data Fusion and Land-cover Mapping using Sentinel-1/-2 Images

no code implementations9 Mar 2021 Yuxing Chen, Lorenzo Bruzzone

For the land-cover mapping task, we assign each pixel a land-cover class by the joint use of pre-trained features and spectral information of the image itself.

Harnessing the linguistic signal to predict scalar inferences

1 code implementation ACL 2020 Sebastian Schuster, Yuxing Chen, Judith Degen

Pragmatic inferences often subtly depend on the presence or absence of linguistic features.

DialectGram: Detecting Dialectal Variation at Multiple Geographic Resolutions

1 code implementation4 Oct 2019 Hang Jiang, Haoshen Hong, Yuxing Chen, Vivek Kulkarni

In this work, we propose a model that enables detection of dialectal variation at multiple levels of geographic resolution obviating the need for a-priori definition of the resolution level.
