landmarker 0.4.0

A PyTorch-based toolkit for (anatomical) landmark detection in images.

Landmarker is a PyTorch-based toolkit for (anatomical) landmark localization in 2D/3D images. It is designed to be easy to use and to provide a flexible framework for state-of-the-art landmark localization algorithms for small and large datasets. Landmarker was developed for landmark detection in medical images. However, it can be used for any type of landmark localization problem.
