Multi-stream Cell Segmentation with Low-level Cues for Multi-modality Images

1 code implementation22 Oct 2023 Wei Lou, Xinyi Yu, Chenyu Liu, Xiang Wan, Guanbin Li, SiQi Liu, Haofeng Li

Afterward, we train a separate segmentation model for each category using the images in the corresponding category.

Diffusion-based Data Augmentation for Nuclei Image Segmentation

1 code implementation22 Oct 2023 Xinyi Yu, Guanbin Li, Wei Lou, SiQi Liu, Xiang Wan, Yan Chen, Haofeng Li

Therefore, augmenting a dataset with only a few labeled images to improve the segmentation performance is of significant research and application value.

Structure Embedded Nucleus Classification for Histopathology Images

no code implementations22 Feb 2023 Wei Lou, Xiang Wan, Guanbin Li, Xiaoying Lou, Chenghang Li, Feng Gao, Haofeng Li

Next, we convert a histopathology image into a graph structure with nuclei as nodes, and build a graph neural network to embed the spatial distribution of nuclei into their representations.

Which Pixel to Annotate: a Label-Efficient Nuclei Segmentation Framework

1 code implementation20 Dec 2022 Wei Lou, Haofeng Li, Guanbin Li, Xiaoguang Han, Xiang Wan

Recently deep neural networks, which require a large amount of annotated samples, have been widely applied in nuclei instance segmentation of H\&E stained pathology images.

Fast Heterogeneous Federated Learning with Hybrid Client Selection

no code implementations10 Aug 2022 Guangyuan Shen, Dehong Gao, Duanxiao Song, Libin Yang, Xukai Zhou, Shirui Pan, Wei Lou, Fang Zhou

We present a novel clustering-based client selection scheme to accelerate the FL convergence by variance reduction.

Variance-Reduced Heterogeneous Federated Learning via Stratified Client Selection

no code implementations15 Jan 2022 Guangyuan Shen, Dehong Gao, Libin Yang, Fang Zhou, Duanxiao Song, Wei Lou, Shirui Pan

However, due to the large variance of the selected subset's update, prior selection approaches with a limited sampling ratio cannot perform well on convergence and accuracy in heterogeneous FL.

Dynamic-OFA: Runtime DNN Architecture Switching for Performance Scaling on Heterogeneous Embedded Platforms

1 code implementation8 May 2021 Wei Lou, Lei Xun, Amin Sabet, Jia Bi, Jonathon Hare, Geoff V. Merrett

However, the training process of such dynamic DNNs can be costly, since platform-aware models of different deployment scenarios must be retrained to become dynamic.
