Od Covidgr: X-Ray Imaging for COVID-19 Detection

Od Covidgr is a collection of X-ray imaging data for COVID-19 detection, published by the ari-dasci organization on GitHub. The repository was last updated in September 2020, providing medical imagery from the early stages of the global pandemic.

Use Cases

• Training convolutional neural networks for binary classification using X-ray image features
• Developing automated screening tools based on pulmonary opacity patterns in radiographs
• Benchmarking computer vision architectures on early-pandemic medical image sets

Strengths

• Specific focus on COVID-19 X-ray imaging
• Maintained by the ari-dasci research group
• Publicly accessible via GitHub for reproducibility

Limitations

• Unknown sample size and class distribution between COVID and non-COVID cases
• Lack of clinical metadata such as patient age, sex, or symptom severity
• Temporal staleness with no updates since late 2020
