ITK Segmentation

ITK is an open-source, cross-platform toolkit for N-dimensional image analysis, segmentation, and registration. The itk-segmentation subpackage provides segmentation algorithms, including level sets, watershed, region growing, and threshold-based methods. Current version 5.4.6 requires Python >=3.8, with ongoing development toward ITK 6.0 (currently in beta). Regular maintenance releases occur approximately quarterly.
