AlbumentationsX is a Python library for image augmentation. It provides high-performance, robust implementations and cutting-edge features for computer vision tasks. Image augmentation is used in deep learning and computer vision to increase the quality of trained models. The purpose of image augmentation is to create new training samples from the existing data.

Licensing

AlbumentationsX offers two license options:

• Commercial license: choose alternative permissions for proprietary software under an agreement covering your team, products, and deployments. Request a quote or email vladimir@albumentations.ai.
• AGPL-3.0-only: available at no charge. The AGPL permits commercial use subject to its terms. Read the license guide.

Commercial, proprietary, internal, or production status alone does not require a commercial license. See the AGPL text and licensing details and history for the applicable terms.

For supplier questionnaires and purchasing documents, see institutional procurement.

Quick Start

# Install the PyTorch build for your platform first. For Linux CPU-only:
pip install "torch>=2.13.0" --index-url https://download.pytorch.org/whl/cpu

# Then install AlbumentationsX with OpenCV.
pip install "albumentationsx[headless]"

import albumentations as A

transform = A.Compose(
    [
        A.RandomCrop(width=256, height=256),
        A.HorizontalFlip(p=0.5),
        A.RandomBrightnessContrast(p=0.2),
    ]
)

Here is an example of how you can apply some pixel-level augmentations to create new images from the original one:

Installation

AlbumentationsX requires Python 3.10 or higher. To install the latest version from PyPI:

Basic Installation

Install the PyTorch build for your CPU, CUDA, or MPS environment before installing AlbumentationsX. For a Linux CPU-only environment:

pip install "torch>=2.13.0" --index-url https://download.pytorch.org/whl/cpu

For CUDA or macOS (MPS), use the matching command from the PyTorch installation selector. AlbumentationsX does not choose or install a PyTorch accelerator build.

If you already have OpenCV installed (any variant), install AlbumentationsX:

pip install -U albumentationsx

Installation with OpenCV

If you don't have OpenCV installed yet, choose the appropriate variant:

# For servers/Docker (no GUI support, lighter package)
pip install -U "albumentationsx[headless]"

# For local development with GUI support (cv2.imshow, etc.)
pip install opencv-python && pip install -U albumentationsx

# For OpenCV with extra algorithms (contrib modules)
pip install opencv-contrib-python && pip install -U albumentationsx

# For contrib + headless
pip install -U "albumentationsx[contrib-headless]"

Note: AlbumentationsX works with any OpenCV variant:

• opencv-python (full version with GUI)
• opencv-python-headless (no GUI, smaller size)
• opencv-contrib-python (with extra modules)
• opencv-contrib-python-headless (contrib + headless)

Choose the one that fits your needs. The library will detect whichever is installed.

pip install albumentationsx installs the base dependency set without PyTorch. It is useful for dependency-only consumers such as documentation builds. Importing albumentations requires the PyTorch build you selected above.

Other installation options are described in the documentation.

Documentation

The full documentation is available at https://albumentations.ai/docs/. For security, release verification, and contributor guides, see the repository documentation.

For AI-assisted augmentation review, AlbumentationsX can also be used through MCP-capable hosts such as Claude Desktop, Cursor, Claude Code, and Codex. The community AlbumentationsX MCP integration lets assistants inspect transforms, validate pipelines, render bounded local preview batches, compare preview runs, collect concrete feedback, and export reproducible AlbumentationsX pipelines.

A simple example

import albumentations as A
import cv2

transform = A.Compose(
    [
        A.RandomCrop(width=256, height=256),
        A.HorizontalFlip(p=0.5),
        A.RandomBrightnessContrast(p=0.2),
    ]
)

image = cv2.imread("image.jpg", cv2.IMREAD_COLOR_RGB)

transformed = transform(image=image)
transformed_image = transformed["image"]

AlbumentationsX collects usage statistics by default to guide product development. See data collection and opt-out.
