Meta-Album Fungi: 15,122 Images of 25 Danish Fungi Species

A dataset of 15,122 standardized 128x128 pixel images across 25 fungi species, sampled from the Danish Fungi 2020 dataset. The data was collected and verified by a network of 3,300 citizen botanists and experts from the Atlas of Danish Fungi repository. The Meta-Album version was created in March 2022.

Use Cases

• Training image classification models for fungi species identification based on the 25 labeled classes.
• Benchmarking few-shot learning algorithms using the standardized, pre-processed image format.
• Developing computer vision models for ecological monitoring and biodiversity studies.
• Researching data collection and verification methodologies involving large-scale citizen science projects.

Strengths

• Contains 15,122 images, providing a substantial sample size for model training.
• Data quality is enhanced by a multi-stage verification process involving 3,300 citizen scientists and expert review.
• Images are uniformly pre-processed to a 128x128 pixel standard, ensuring consistency.

Limitations

• Description metadata is limited; actual data quality and potential class imbalances require manual inspection after download.
• The dataset is a curated subset of 25 classes from a larger source, which may limit generalizability to other fungi species.
• Image cropping and resizing to a uniform small size may have removed contextual details present in the original photographs.
