Exploring Effective Priors and Efficient Models for Weakly-Supervised Change Detection

1 code implementation20 Jul 2023 Zhenghui Zhao, Lixiang Ru, Chen Wu

Specifically, change missing refer to the situation that the WSCD model fails to predict any changed pixels, even though the image-level label indicates changed, and vice versa for change fabricating.

Token Contrast for Weakly-Supervised Semantic Segmentation

1 code implementation CVPR 2023 Lixiang Ru, Heliang Zheng, Yibing Zhan, Bo Du

Secondly, to further differentiate the low-confidence regions in CAM, we devised a Class Token Contrast module (CTC) inspired by the fact that class tokens in ViT can capture high-level semantics.

Learning Affinity from Attention: End-to-End Weakly-Supervised Semantic Segmentation with Transformers

1 code implementation CVPR 2022 Lixiang Ru, Yibing Zhan, Baosheng Yu, Bo Du

Motivated by the inherent consistency between the self-attention in Transformers and the semantic affinity, we propose an Affinity from Attention (AFA) module to learn semantic affinity from the multi-head self-attention (MHSA) in Transformers.

Weakly-Supervised Semantic Segmentation with Visual Words Learning and Hybrid Pooling

1 code implementation10 Feb 2022 Lixiang Ru, Bo Du, Yibing Zhan, Chen Wu

In the visual words learning module, we counter the first problem by enforcing the classification network to learn fine-grained visual word labels so that more object extents could be discovered.

An Investigation of Traffic Density Changes inside Wuhan during the COVID-19 Epidemic with GF-2 Time-Series Images

no code implementations26 Jun 2020 Chen Wu, Yinong Guo, HaoNan Guo, Jingwen Yuan, Lixiang Ru, Hongruixuan Chen, Bo Du, Liangpei Zhang

The significant reduction and recovery of traffic density indicates that the lockdown policy in Wuhan show effectiveness in controlling human transmission inside the city, and the city returned to normal after lockdown lift.

Multi-Temporal Scene Classification and Scene Change Detection with Correlation based Fusion

1 code implementation3 Jun 2020 Lixiang Ru, Bo Du, Chen Wu

In this work, we proposed a CorrFusion module that fuses the highly correlated components in bi-temporal feature embeddings.
