Pill Image Collection available for open access download
Pill Image Collection is now open access and available from the NLM Data Distribution webpage https://www.nlm.nih.gov/databases/download/data_distrib_main.html.
- The Pill Image database is a collection of curated, freely available, high-quality digital images of prescription pills and associated data. Examples of pills are capsules and tablets intended for oral use.
- Photographs of pills for this collection were taken under laboratory lighting conditions, from a camera directly above the front and the back faces of the pill, at high resolution, and using specialized digital macro-photography techniques. Image segmentation algorithms were then applied to create the JPEG images in the database.
The collection contains two sets of pill images:
1) more than 4,000 reference pill images taken under controlled light conditions
2) more than 133,000 consumer-grade pill images for training pill image recognition algorithms
The pill images are no longer updated. The project was discontinued in 2018.
