CVAugmentor

CVAugmentor is a Python package designed for augmenting images and videos, making it easier to enhance and modify visual data for computer vision tasks. It provides a collection of utilities that automate transformations such as flipping, rotation, scaling, color adjustments, and more.

Available augmentations are:

• no_augmentation
• flip
• zoom
• rotate
• shear
• grayscale
• hue
• saturation
• brightness
• exposure
• blur
• noise
• cutout
• negative

Installation

This package is built with Python 3.12.8.

The simplest way to install it is via pip. Run the following command:

pip install CVAugmentor

Alternatively, you can install it manually by cloning the repository and running the installation. Use the following steps:

git clone git@github.com:AliKHaliliT/CVAugmentor.git  # With SSH
cd CVAugmentor
pip install -r requirements.txt
pip install .

Usage

For a comprehensive guide on how to use the package, please refer to the documentation.

The documentation is kept up-to-date and is automatically generated whenever a change is made to the package through the GitHub Actions workflow.

The provided pipeline should be sufficient for most use cases:

from CVAugmentor import Pipeline


p = Pipeline()

If you require custom functionality, you can also import the augmentations directly:

from CVAugmentor.assets.augmentations._blur import Blur


blur_instance = Blur()

Examples

Single Image Augmentation

from CVAugmentor import Augmentations as aug
from CVAugmentor import Pipeline


## Define the augmentations
augmentations = {
    "blur": aug.Blur(2.5),
    "brightness": aug.Brightness(0.25),
    "cutout": aug.Cutout(max_size=64, max_count=6),
    "expsure": aug.Exposure(0.3),
    "flip": aug.Flip(),
    "grayscale": aug.Grayscale(),
    "hue": aug.Hue(-360),
    "negative": aug.Negative(),
    "no_augmentation": aug.NoAugmentation(),
    "noise": aug.Noise(0.4),
    "rotate": aug.Rotate(),
    "saturation": aug.Saturation(0.5),
    "shear": aug.Shear((0.2, 0.2)),
    "zoom": aug.Zoom(),
}


## Create a Pipeline object
p = Pipeline()

## Augment the image
p.augment(input_path="local_util_resources/samples/images/0.png", 
          output_path="local_util_resources/experiments/single_image/0.png", 
          target="image", 
          process_type="single", 
          mode="sequential", 
          augmentations=augmentations, 
          aug_verbose=True)
