Summary

• What is new: Introduction of a novel task named astrocyte segmentation with a new dataset (IAI704) and a frequency domain denoising network (FDNet) for image analysis.
• Why this is important: Astrocytes, essential for neuronal metabolism studies, are difficult to observe in microscopy images due to blending with the background and interference from dead cells, media sediments, and cell debris.
• What the research proposes: A new dataset, IAI704, for astrocyte segmentation is introduced alongside FDNet, which employs contextual information fusion, attention mechanisms, and frequency domain transformation to improve segmentation accuracy.
• Results: FDNet outperforms existing state-of-the-art methods in accurately segmenting astrocytes, offering valuable insights for iPSC differentiation progress prediction.
