Background:

The comet assay is crucial for quantifying DNA damage in genotoxicity testing.
Current image analysis relies on traditional methods, often lacking efficiency and accuracy.
Deep learning (DL) offers potential for improved image analysis in biological assays.

Purpose of the Study:

To introduce DeepComet, a DL-based method for comet assay image segmentation.
To develop and validate a comprehensive dataset for training and testing comet segmentation algorithms.
To compare DeepComet's performance against existing state-of-the-art methods.

Main Methods:

Development of a DL model (DeepComet) for comet segmentation.
Creation of a new dataset with 1037 comet assay images and 8271 annotated comet objects.
Evaluation using average precision (AP) and comparison with other automated segmentation tools.

Main Results:

DeepComet achieved high average precision in comet segmentation.
The DL method demonstrated strong performance compared to existing automated programs.
DeepComet showed high correlation with a commercial comet analysis tool.

Conclusions:

DeepComet provides a robust and accurate solution for comet assay image segmentation.
The developed dataset facilitates further research in automated comet assay analysis.
DeepComet shows promise for practical applications in genotoxicity assessment.
