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

数据说明

Data related to the Publication “Effect of surface-partial-volume correction and adaptive threshold on segmentation of uroliths in computed tomography”

101 Uroliths were ex-vivo (volume and diameter) and CT imaging was performed. Data consists of

• measured ground truth volume

• measured ground truth diameter

• CT imaging of all stones

• stone composition (when available)

Data ist provided as a csv table, and as MATLAB .mat file.

CSV Table Data

Table containing a row for each of the 101 uroliths with colums: ID, Volume, Diameter and Stone Type.

Matlab Data

Matlab structure array of the 101 uroliths with the following fields:

    gt_diam:      diameter (ground truth)

    gt_vol:          volume (ground truth)

    imgdata       3D data from CT imaging      

    voxsiz          voxel size in mm (x y z)

    voxvol_mL   size per voxel in milliliter

Some uroliths have cavities, these are filled with NaN values in imgdata
