Group R-CNN for Weakly Semi-supervised Object Detection with Points

1 code implementation CVPR 2022 Shilong Zhang, Zhuoran Yu, Liyang Liu, Xinjiang Wang, Aojun Zhou, Kai Chen

The core of this task is to train a point-to-box regressor on well-labeled images that can be used to predict credible bounding boxes for each point annotation.

Pseudo-mask Matters in Weakly-supervised Semantic Segmentation

2 code implementations ICCV 2021 Yi Li, Zhanghui Kuang, Liyang Liu, Yimin Chen, Wayne Zhang

For these matters, we propose the following designs to push the performance to new state-of-art: (i) Coefficient of Variation Smoothing to smooth the CAMs adaptively; (ii) Proportional Pseudo-mask Generation to project the expanded CAMs to pseudo-mask based on a new metric indicating the importance of each class on each location, instead of the scores trained from binary classifiers.

Decomposing Disease Descriptions for Enhanced Pathology Detection: A Multi-Aspect Vision-Language Pre-training Framework

1 code implementation12 Mar 2024 Vu Minh Hieu Phan, Yutong Xie, Yuankai Qi, Lingqiao Liu, Liyang Liu, BoWen Zhang, Zhibin Liao, Qi Wu, Minh-Son To, Johan W. Verjans

Medical vision language pre-training (VLP) has emerged as a frontier of research, enabling zero-shot pathological recognition by comparing the query image with the textual descriptions for each disease.

BPKD: Boundary Privileged Knowledge Distillation For Semantic Segmentation

1 code implementation13 Jun 2023 Liyang Liu, Zihan Wang, Minh Hieu Phan, BoWen Zhang, Jinchao Ge, Yifan Liu

Current knowledge distillation approaches in semantic segmentation tend to adopt a holistic approach that treats all spatial locations equally.

Diverse Message Passing for Attribute with Heterophily

no code implementations NeurIPS 2021 Liang Yang, Mengzhe Li, Liyang Liu, bingxin niu, Chuan Wang, Xiaochun Cao, Yuanfang Guo

Based on this attribute homophily rate, we propose a Diverse Message Passing (DMP) framework, which specifies every attribute propagation weight on each edge.
