Area of Science:

  • Biomedical imaging
  • Deep learning
  • Cell biology

Background:

  • Manual segmentation of mitochondria in 3D EM datasets is time-consuming and challenging due to their size and ambiguous borders.
  • Existing deep learning segmentation tools are optimized for either 2D low-resolution or 3D high-resolution imaging, failing to address the specific needs of 3D mitochondria segmentation.
  • Accurate segmentation of 3D mitochondria is crucial for understanding cellular function and dynamics.

Conclusions:

  • SKOOTS significantly improves the accuracy and efficiency of 3D mitochondria segmentation in electron microscopy data.
  • The developed method extends to segment objects in 3D light microscopy datasets, broadening its applicability.
  • This work enhances accessibility for 3D biomedical image analysis and provides a valuable new tool for researchers.
