ITK-SNAP

ITK-SNAP is a multi-platform software application designed for segmenting structures within 3D and 4D biomedical images. Initially developed at the University of North Carolina, it emphasizes ease of use and focuses specifically on image segmentation tasks. Led by researchers at the Penn Image Computing and Science Laboratory (PICSL) at the University of Pennsylvania, ITK-SNAP offers semi-automatic segmentation through active contour methods, manual delineation, and image navigation. It supports various 3D image formats like NIfTI and DICOM, allowing concurrent viewing and segmentation of multiple images. Features include manual and automatic image registration, between-slice segmentation interpolation, and a 3D cut-plane tool. With a focus on user interaction, ITK-SNAP prioritizes a streamlined user interface. It is intended for researchers and clinicians working with medical imaging data.
