Our great sponsors
  • SonarQube - Static code analysis for 29 languages.
  • JetBrains - Developer Ecosystem Survey 2022
  • Scout APM - Less time debugging, more time building
  • elixir-opencv

    OpenCv NIF Bindings for Erlang/Elixir.

    For OpenCV specifically, it looks like this repo exists https://github.com/ConnorRigby/elixir-opencv but is apparently abandoned and archived. (Currently almost nothing works)

  • mogrify

    Image processing in Elixir (ImageMagick command line wrapper)

    https://github.com/route/mogrify Probably the most feature-rich one, and makes use of pipes. But it's just a wrapper around ImageMagick and requires IM to be installed, which I'm not a huge fan of.

  • SonarQube

    Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

  • imagineer

    Image processing in Elixir

    https://github.com/tyre/imagineer Only supports reading/writing PNGs, and is abandoned

  • eimp

    Erlang Image Manipulation Process

    https://github.com/processone/eimp Searching instead for Erlang yields a few more results, such as this library which seems to be under very active development. However, the features seem limited, and it's all done with C code running in an external program, instead of via NIF. Pretty odd.

  • erl_img

    Read/write image library for Erlang

    https://github.com/evanmiller/erl_img And finally, there's this, which seems kinda feature-rich and is completely written in Erlang, so that's kind of cool. However, it's extremely old. It's used in this, https://github.com/proxeld/img_proc which adds more features but directly specifies this project is not intended to be used. It's more for education and testing purpose

  • img_proc

    Concurrent image processing in Erlang.

  • matrex

    A blazing fast matrix library for Elixir/Erlang with C implementation using CBLAS.

    Finally, there's Matrex https://github.com/versilov/matrex which seems very performant and has some awesome features like command-line rending of heatmaps. I wonder if it could be useful for image processing in the same way that NumPy is used in Python's OpenCV.

  • JetBrains
