ITK VS OpenCV

Compare ITK vs OpenCV and see what are their differences.

ITK

Insight Toolkit (ITK) -- Official Repository. ITK builds on a proven, spatially-oriented architecture for processing, segmentation, and registration of scientific images in two, three, or more dimensions. (by InsightSoftwareConsortium)

OpenCV

Open Source Computer Vision Library (by opencv)

  • Ask HN: What is a cool technology to learn?

    Yeah, Prolog is pretty cool!

    Another technology I found interesting too learn is ITK (https://itk.org/). You need a different mindset using ITK than other image processing libraries.

    Lisp is cool as well.

    And fully homomorphic encryption.

    VTK is a powerful visualization package, but it's more for working with 3D FEM/CFD data. There are lots of things in there though, so it may be useful. The sister project Paraview is an application which can be used to work with data interactively. Both have great Python support. There is also ITK which is focused on with image data, like medical scans - never used it, though.
