COSEM: Cell Organelle Segmentation in Electron Microscopy

High-resolution electron microscopy images of subcellular structures, published on the AWS Open Data registry. The dataset is provided by the Janelia Research Campus and is licensed under CC-BY-4.0.

Use Cases

• Train a semantic segmentation model to identify organelles (inferred from domain, verify after download)
• Benchmark instance segmentation algorithms on biological images (inferred from domain, verify after download)
• Analyze subcellular morphology and spatial relationships (inferred from domain, verify after download)

Strengths

• Published on the AWS Open Data registry.
• Provided by the Janelia Research Campus.
• Available under a permissive CC-BY-4.0 license.

Limitations

• Metadata is minimal; actual content requires verification after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
