  • Modern CMake

    > If you think your project will have more than half a dozen developers then you should probably start thinking about something like...

    CMake was created in 2000 with large, cross-platform projects involving multiple organizations in mind. The development was funded by the National Library of Medicine (NLM) for the ITK project (https://github.com/InsightSoftwareConsortium/ITK). As of 2025, ITK consists of millions of lines of code and has received contributions from hundreds of developers. Other projects of similar scale include VTK and ParaView.

  • How to raise the quality of scientific Jupyter notebooks
    9 projects | dev.to | 11 Jan 2023
    Jupyter has emerged as a fundamental component in artificial intelligence (AI) solution development and scientific inquiry. Jupyter notebooks are prevelant in modern education, commercial applications, and academic research. The Insight Toolkit (ITK) is an open source, cross-platform toolkit for N-dimensional processing, segmentation, and registration used to obtain quantitative insights from medical, biomicroscopy, material science, and geoscience images. The ITK community highly values scientific reproducibility and software sustainability. As a result, advanced computational methods in the toolkit have a dramatically larger impact because they can be reproducibly applied in derived research or commercial applications.
  • Holy shit, it really seems to be working!
    1 project | /r/lostarkgame | 19 Jun 2022
    It also depends heavily on the toolchain. One of the first successful toolkits used to circumvent image-based security measures was ITK, originally a toolkit for medical image processing. That's not even using AI (at least back then). Here you build "piplines" by lego'ing together functions like building blocks, there are rules to it, but the sleek interface design make it very versatile. It was a nightmare to devise ways to counteract, since the crucial processing steps could easily be switched around as long as the linear algebra made sense. And when you have a toolchain excelling in fourier-space based analysis and interaction, the linear algebra makes sense in a lot of different orders of doing steps.
  • Ask HN: What is a cool technology to learn?
    2 projects | news.ycombinator.com | 1 Jul 2021
    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.

  • Give me a starting nudge: microscopy image processing in python
    3 projects | /r/Python | 27 May 2021
    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.
