State-of-the-art and curated Computer Vision algorithms for AI.

Kornia AI is on the mission to leverage and democratize the next generation of Computer Vision tools and Deep Learning libraries
within the context of an Open Source community.

.. code:: python

   >>> import kornia.geometry as K
   >>> registrator = K.ImageRegistrator('similarity')
   >>> model = registrator.register(img1, img2)

Ready to use with state-of-the art Deep Learning models:

DexiNed edge detection model.

.. code-block:: python

      image = kornia.utils.sample.get_sample_images()[0][None]
      model = DexiNedBuilder.build()
      model.save(image)

RTDETRDetector for object detection.

.. code-block:: python

      image = kornia.utils.sample.get_sample_images()[0][None]
      model = RTDETRDetectorBuilder.build()
      model.save(image)

BoxMotTracker for object tracking.

.. code-block:: python

      import kornia
      image = kornia.utils.sample.get_sample_images()[0][None]
      model = BoxMotTracker()
      for i in range(4):
         model.update(image)
      model.save(image)

Vision Transformer for image classification.

.. code:: python

   >>> import torch.nn as nn
   >>> import kornia.contrib as K
   >>> classifier = nn.Sequential(
   ...   K.VisionTransformer(image_size=224, patch_size=16),
   ...   K.ClassificationHead(num_classes=1000),
   ... )
   >>> logits = classifier(img)    # BxN
   >>> scores = logits.argmax(-1)  # B

Multi-framework support
-----------------------

You can now use Kornia with `NumPy <https://numpy.org/>`_, `TensorFlow <https://www.tensorflow.org/>`_, and `JAX <https://jax.readthedocs.io/en/latest/index.html>`_.

.. code:: python

  >>> import kornia
  >>> tf_kornia = kornia.to_tensorflow()
