Multiclass Spinal Cord Tumor Segmentation on MRI with Deep Learning

no code implementations23 Dec 2020 Andreanne Lemay, Charley Gros, Zhizheng Zhuo, Jie Zhang, Yunyun Duan, Julien Cohen-Adad, Yaou Liu

To the best of our knowledge, this is the first fully automatic deep learning model for spinal cord tumor segmentation.

Positive-unlabeled learning for binary and multi-class cell detection in histopathology images with incomplete annotations

1 code implementation16 Feb 2023 Zipei Zhao, Fengqian Pang, Yaou Liu, Zhiwen Liu, Chuyang Ye

Typically, to train CNN-based cell detection models, every positive instance in the training images needs to be annotated, and instances that are not labeled as positive are considered negative samples.

One-Shot Segmentation of Novel White Matter Tracts via Extensive Data Augmentation

1 code implementation13 Mar 2023 Wan Liu, Qi Lu, Zhizheng Zhuo, Yaou Liu, Chuyang Ye

However, accurate segmentation of novel WM tracts can still be challenging in the one-shot setting, where only one scan is annotated for the novel WM tracts.

Unsupervised Brain Tumor Segmentation with Image-based Prompts

no code implementations4 Apr 2023 Xinru Zhang, Ni Ou, Chenghao Liu, Zhizheng Zhuo, Yaou Liu, Chuyang Ye

Specifically, instead of directly training a model for brain tumor segmentation with a large amount of annotated data, we seek to train a model that can answer the question: is a voxel in the input image associated with tumor-like hyper-/hypo-intensity?
