源站 README 摘录(使用方式)
COVID-19 Posteroanterior Chest X-Ray fused (CPCXR) dataset
The dataset is genrated by the fusion of three publicly available datasets: COVID-19 cxr image [1], Radiological Society of North America (RSNA) [2], and U.S. national library of medicine (USNLM) collected Montgomery country - NLM(MC) [3]. The dataset consists of samples of diseases labeled as COVID-19, Tuberculosis, Other pneumonia (SARS, MERS, etc.), and Normal.
The dataset can be utilized to train an evaulate deep learning and machine learning models as binary and multi-class classification problem.
The complete dataset is available here.
Dataset description
| Class | Label | Samples |
|---|---|---|
| Normal | 0 | 533 |
| COVID-19 | 1 | 108 |
| Other pneumonia | 2 | 515 |
| Tuberculosis | 3 | 58 |

数据加载示例(图像类)
from PIL import Image
import glob, os
files = (glob.glob(os.path.join(path, "**", "*.png"), recursive=True)
+ glob.glob(os.path.join(path, "**", "*.jpg"), recursive=True)
+ glob.glob(os.path.join(path, "**", "*.tif"), recursive=True))
print("图像文件数:", len(files))
img = Image.open(files[0]); print("尺寸/模式:", img.size, img.mode)
# torchvision Dataset 方式:
# from torchvision import datasets
# 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。
