Aug Tool is a Python library available on PyPI that simplifies image data augmentation for machine learning tasks, compatible with TensorFlow, PyTorch, and the YOLO library.
pip install aug-toolTo install "aug-tool", you can use pip, the Python package manager. Open a terminal or command prompt and run the following command:
- Supports various image augmentation techniques suitable for real environment conditions, such as adding noise, scaling, shifting, and more.
- Provides convenient integration with popular machine learning libraries such as TensorFlow, Keras, PyTorch, etc.
- Allows augmentation of both images and their annotation files in formats such as XML, or TXT.
- Customizable augmentation parameters, including rotation angle, scaling factor, flipping direction, and more.

class Augmentation(object):
def __init__(self, open_data_path:str, save_file_name:str, number_of_aug:int, x_shift:int, y_shift:int) -> None:
"""
This is an initialization function that takes in parameters for data augmentation and saves the
augmented data and annotations to a specified file path.
:param open_data_path: The path to the directory containing the original data to be augmented
:type open_data_path: str
:param save_file_name: The name of the folder where the augmented data will be saved
:type save_file_name: str
:param number_of_aug: The number of times the image and its corresponding annotation will be
augmented
:type number_of_aug: int
:param x_shift: The amount of horizontal shift to apply during image augmentation
:type x_shift: int
:param y_shift: y_shift is a parameter that determines the maximum number of pixels by which an
image can be shifted vertically during data augmentation
:type y_shift: int
""" The __init__ method of the augmentation class performs the initialization and processing steps. This process can be divided into three parts:
In the first part, the method creates the necessary file names and initializes the folder structure for storing the augmented images. This ensures a well-organized output for the augmented data.
# It creates a folder to save inside
self.create_dest_folder(self.target_file_name)
# All the data in the file is taken and augmented in a loop
for data_path in self.create_list_of_data(open_data_path = open_data_path):
# The image and label file with the same name as image is opened once
image = self.label_factory(data_path[:-4])
label = self.image_factory(data_path)
# The augmentation process is performed as much as the `number_of_aug` value from the user
for num in range(number_of_aug):
# The name of new file that will be augmented is created
data_name = data_path.split("\\")[-1][:-4] + "_aug" + str(num + 1))Here, The self.create_dest_folder method is responsible for creating the output folder if it doesn't already exist. self.create_list_of_data stores the path of the files which will be augmented . The loop iterates over the files in the self.create_list_of_data list and obtains the paths to the corresponding image and label files. The self.label_factory and self.image_factory methods are responsible for opening the image and label files, respectively.
The second part of the __init__ method performs the actual augmentation processing of images. Within a nested loop, the augmentation techniques are applied to the image to generate multiple augmented versions of the data.
# The augmented image is created acording values that given users
aug_image = dataAugmentor.ImgAug(image=image,
x_shift=x_shift,
y_shift=y_shift).image_aug
# The augmented image is saved on target file
dataSaver.ImgSav(target_file_path = self.target_file_name,
img_aug = aug_image,
data_name=data_name)The third part of the __init__ method performs the actual augmentation processing of labels. Within a nested loop, the augmentation techniques are applied to the label data to generate multiple augmented versions of the data.
# If the extension of the read label file is '.xml', it is processed here
if self.ann.ext == ".xml":
ann_aug = dataAugmentor.XmlAug(name=data_name,
annotate= label.data,
x_shift=x_shift,
y_shift=y_shift)
dataSaver.XmlSav(target_file_path = self.target_file_name,
ann_aug=ann_aug.annotate,
data_name=data_name)
# If the extension of the read label file is '.txt', it is processed here
elif self.ann.ext == ".txt":
ann_aug = dataAugmentor.TxtAug(
annotate= label.data,
x_shift=x_shift,
y_shift=y_shift,
width=aug_image.width,
height=aug_image.height).aug_anotate
