COVID-19 image data collection
We are building a database of COVID-19 cases with chest X-ray or CT images. We are looking for COVID-19 cases as well as MERS, SARS, and ARDS.
All images and data will be released publicly in this GitHub repo. Currently we are building the database with images from publications as they are images that are already available.

Contribute
- We can extract images from publications. Help identify publications which are not already included using a GitHub issue (DOIs we have are listed in the metadata file). There is a searchable database of COVID-19 papers here, and a non-searchable one (requires download) here.
- Submit data to https://radiopedia.org/ or https://www.sirm.org/category/senza-categoria/covid-19/ (we can scrape the data from them)
- Provide bounding box/masks for the detection of problematic regions in images already collected.
- See CONTRIBUTING.md for more information on the metadata schema.
Formats: For chest X-ray dcm, jpg, or png are preferred. For CT nifti (in gzip format) is preferred but also dcms. Please contact with any questions.

from PIL import Image

files = (glob.glob(os.path.join(path, "**", "*.png"), recursive=True)
+ glob.glob(os.path.join(path, "**", "*.jpg"), recursive=True)

img = Image.open(files[0]); print("尺寸/模式:", img.size, img.mode)

# ds = datasets.ImageFolder(path) # 要求 子目录=类别
目录组织与标注格式以源站说明和下载后实际文件为准。
