DiffUCD:Unsupervised Hyperspectral Image Change Detection with Semantic Correlation Diffusion Model

no code implementations21 May 2023 Xiangrong Zhang, Shunli Tian, Guanchun Wang, Huiyu Zhou, Licheng Jiao

In this work, we extend the diffusion model's application to the HSI-CD field and propose a novel unsupervised HSI-CD with semantic correlation diffusion model (DiffUCD).

SoftMatch Distance: A Novel Distance for Weakly-Supervised Trend Change Detection in Bi-Temporal Images

no code implementations8 Mar 2023 Yuqun Yang, Xu Tang, Xiangrong Zhang, Jingjing Ma, Licheng Jiao

Therefore, there is a novel solution that intuitively dividing changes into three trends (``appear'', ``disappear'' and ``transform'') instead of semantic categories, named it trend change detection (TCD) in this paper.

Absolute Wrong Makes Better: Boosting Weakly Supervised Object Detection via Negative Deterministic Information

no code implementations21 Apr 2022 Guanchun Wang, Xiangrong Zhang, Zelin Peng, Xu Tang, Huiyu Zhou, Licheng Jiao

In the exploiting stage, we utilize the extracted NDI to construct a novel negative contrastive learning mechanism and a negative guided instance selection strategy for dealing with the issues of part domination and missing instances, respectively.

Unsupervised Outlier Detection using Memory and Contrastive Learning

no code implementations27 Jul 2021 Ning Huyan, Dou Quan, Xiangrong Zhang, Xuefeng Liang, Jocelyn Chanussot, Licheng Jiao

Instead, we think outlier detection can be done in the feature space by measuring the feature distance between outliers and inliers.

Semantic Attention and Scale Complementary Network for Instance Segmentation in Remote Sensing Images

no code implementations25 Jul 2021 Tianyang Zhang, Xiangrong Zhang, Peng Zhu, Xu Tang, Chen Li, Licheng Jiao, Huiyu Zhou

To address the above problems, we propose an end-to-end multi-category instance segmentation model, namely Semantic Attention and Scale Complementary Network, which mainly consists of a Semantic Attention (SEA) module and a Scale Complementary Mask Branch (SCMB).
