9 Best Free and Open Source Image Processing Libraries

Last Updated on May 23, 2022

When we think of great open source image processing software, tools like GIMP, Blender, and Inkscape instantly spring to mind.

We’ve covered a huge raft of graphics software for Linux with a splurge of recommended roundups. But there are some categories of graphics software which attract less exposure. Image processing libraries is a good example. This type of software performs image processing operations. They can perform arithmetic, histograms, convolution, morphological operations, frequency filtering, colour, resampling, statistics, and much more.

Good libraries support a wide range of image formats such as JPEG, TIFF, PNG, WebP, FITS, Matlab, OpenEXR, PDF, SVG, HDR, PPM, CSV, GIF, Analyze, NIfTI, DeepZoom, and OpenSlide.

In this article we recommend the finest image processing libraries. Our recommendations are captured in a legendary LinuxLinks chart. As you can see, there are many great libraries for developers. Only free and open source software is eligible for inclusion.
