Area of Science:

Computational Biology
Machine Learning
Biomedical Imaging

Background:

Deep learning models excel in performance but require large annotated datasets.
Reducing annotation burden is crucial for practical deep learning applications.
Nuclei counter-stain data offers a source for programmatic cell location extraction.

Purpose of the Study:

To develop a weakly-supervised training method for single-cell segmentation models.
To introduce a novel self-learning strategy called collaborative knowledge sharing.
To address the challenge of limited annotated data in cell image analysis.

Main Methods:

Proposed a self-learning method: collaborative knowledge sharing.
Utilized rough cell locations as the sole training labels.
Employed two distinct models: a principal (object detection) and a collaborator (semantic segmentation).

Main Results:

Demonstrated effectiveness on the LIVECell and A431 datasets.
Showcased the viability of using nuclei counter-stain data for cell location labeling.
Validated the collaborative knowledge sharing strategy in a weakly-supervised setting.

Conclusions:

Collaborative knowledge sharing effectively reduces annotation requirements for single-cell segmentation.
The proposed method offers a practical solution for leveraging readily available biomedical image data.
This approach advances weakly-supervised learning in the field of cell image analysis.
