custom dataset from directory

[Data-Iab]

• New feature : Create image data iterator from path. Useful for:
  • Calibration: when the dataset iterator is not defined.
  • testing: when you need to test with some images stored is a folder.

caution : the iterator does not take into consideration frames synchronization when the class is instantiated with a dict

from alodataset import FromDirectoryDataset


# You can either pass a dict or a list of paths
# from list of paths.
path1 = "/PATH/TO/DATA/DIR1"
path2 = "/PATH/TO/DATA/DIR2"

data = FromDirectoryDataset(dirs=[path1, path2])
img = data[0]

# from dict of list of paths.
path0 = "/PATH/TO/DATA/DIR0"
path1 = "/PATH/TO/DATA/DIR1"
path2 = "/PATH/TO/DATA/DIR2"
path3 = "/PATH/TO/DATA/DIR3"

data = FromDirectoryDataset(dirs={"key1": [path0, path1], "key2": [path2, path3]])
img_key1 = data[0]["key1"]
img_key2 = data[0]["key2"]
