SA-MixNet: Structure-aware Mixup and Invariance Learning for Scribble-supervised Road Extraction in Remote Sensing Images

no code implementations3 Mar 2024 Jie Feng, Hao Huang, Junpeng Zhang, Weisheng Dong, Dingwen Zhang, Licheng Jiao

To eliminate the reliance on such priors, we propose a novel Structure-aware Mixup and Invariance Learning framework (SA-MixNet) for weakly supervised road extraction that improves the model invariance in a data-driven manner.

Inferring cell-specific lncRNA regulation with single-cell RNA-sequencing data in the developing human neocortex

1 code implementation15 Nov 2022 Meng Huang, Jiangtao Ma, Changzhou Long, Junpeng Zhang, Xiucai Ye, Tetsuya Sakurai

However, to analyze lncRNA regulation regarding individual cells, we focus on single-cell RNA-sequencing (scRNA-seq) data instead of bulk data.

Knowledge Distillation for Oriented Object Detection on Aerial Images

no code implementations20 Jun 2022 Yicheng Xiao, Junpeng Zhang

Transferring the category information is achieved by knowledge distillation on predicted probability distribution, and a soft regression loss is adopted for handling displacement in location information transfer.

MidNet: An Anchor-and-Angle-Free Detector for Oriented Ship Detection in Aerial Images

no code implementations22 Nov 2021 Feng Jie, Yuping Liang, Junpeng Zhang, Xiangrong Zhang, Quanhe Yao, Licheng Jiao

Ship detection in aerial images remains an active yet challenging task due to arbitrary object orientation and complex background from a bird's-eye perspective.


Online Structured Sparsity-based Moving Object Detection from Satellite Videos

no code implementations29 Nov 2019 Junpeng Zhang, Xiuping Jia, Jiankun Hu, Jocelyn Chanussot

O-LSD reformulates the batch-based low-rank matrix decomposition with the structured sparse penalty to its equivalent frame-wise separable counterpart, which then defines a stochastic optimization problem for online subspace basis estimation.

Error Bounded Foreground and Background Modeling for Moving Object Detection in Satellite Videos

no code implementations26 Aug 2019 Junpeng Zhang, Xiuping Jia, Jiankun Hu

It is integrated with structured sparsity regularization to achieve background subtraction in the developed method of Low-rank and Structured Sparse Decomposition (LSD).
