Connected Components 3D

Connected Components 3D (cc3d) is a Python library for performing connected component labeling on discrete and continuous multilabel 3D and 2D images. It efficiently handles 26, 18, and 6 connected variants for 3D images, and 4 or 8 connected variants for 2D images, including support for periodic boundaries. The library is currently at version 3.26.1 and is actively maintained, offering significant performance improvements over general-purpose libraries for multi-label and large volumetric datasets.
