Volumentations 3D

3D Volume data augmentation package inspired by albumentations.

Volumentations is a working project, which originated from the following Git repositories:

• Original: https://github.com/albumentations-team/albumentations
• 3D Conversion: https://github.com/ashawkey/volumentations
• Continued Development: https://github.com/ZFTurbo/volumentations

Nevertheless, if you are using this subpackage, please give credit to all authors including ashawkey, ZFTurbo, qubvel and muellerdo.

Initially inspired by albumentations library for augmentation of 2D images.

Installation

pip install volumentations-3D

Simple Example

from volumentations import *

def get_augmentation(patch_size):
    return Compose([
        Rotate((-15, 15), (0, 0), (0, 0), p=0.5),
        RandomCropFromBorders(crop_value=0.1, p=0.5),
        ElasticTransform((0, 0.25), interpolation=2, p=0.1),
        Resize(patch_size, interpolation=1, resize_type=0, always_apply=True, p=1.0),
        Flip(0, p=0.5),
        Flip(1, p=0.5),
        Flip(2, p=0.5),
        RandomRotate90((1, 2), p=0.5),
        GaussianNoise(var_limit=(0, 5), p=0.2),
        RandomGamma(gamma_limit=(80, 120), p=0.2),
    ], p=1.0)

aug = get_augmentation((64, 128, 128))

img = np.random.randint(0, 255, size=(128, 256, 256), dtype=np.uint8)
lbl = np.random.randint(0, 1, size=(128, 256, 256), dtype=np.uint8)

# with mask
data = {'image': img, 'mask': lbl}
aug_data = aug(**data)
img, lbl = aug_data['image'], aug_data['mask']

# without mask
data = {'image': img}
aug_data = aug(**data)
img = aug_data['image']

• Check working usage example in tst_volumentations_type_1.py
• Added another usage example / testing in tst_volumentations_type_2.py

Difference from initial version

• Diverse bug fixes.
• Implemented multiple augmentations.
• Approximation enhancements to be closer to Albumentations.

Implemented 3D augmentations
