Together with the core ITK codebase, a number of other projects and frameworks are maintained allowing to leverage the power of ITK beyond its natural boundaries:
ITK/VTK Viewer is a web-based image, mesh, and point set viewer.
itk-viewer is a multi-dimensional web-based image, mesh, and point set viewer.
ITK-Wasm combines ITK and WebAssembly to enable high-performance spatial analysis in a web browser or system-level environments and reproducible execution across programming languages and hardware architectures.
itkwidgets is an elegant Python interface for visualization on the web platform to interactively generate insights into multidimensional images, point sets, and geometry.
Other legacy projects that offered ITK’s power through other interfaces or sets of pipelines were:
Praxix was a collection of command line programs for image processing using ITK.
ITK One Shot was a collecion of short programs to perform specific operations on images.
ITKApps were a variety of applications written with ITK, ranging from simple uses of the toolkit to complex and GUI-based applications.
