napari is a fast, interactive, multi-dimensional image viewer for Python. It’s designed for browsing, annotating, and analyzing large multi-dimensional images. It’s built on top of
Qt (for the GUI),
vispy (for performant GPU-based rendering), and the scientific Python stack (e.g.
scipy). It includes critical viewer features out-of-the-box, such as support for large multi-dimensional data, and layering and annotation. By integrating closely with the Python ecosystem, napari can be easily coupled to leading machine learning and image analysis tools (e.g.
PyTorch), enabling more user-friendly automated analysis.
