Hi HN, I'm one of the main developers of G'MIC (GREYC's Magic for Image Computing), an open-source image processing framework we've been building for over a decade. G'MIC provides hundreds of image processing filters and tools, available as a command-line tool, a GIMP/Krita plugin, a standalone GUI, and a C++ library for developers.

We just released G'MIC 3.5.3, which brings new filters, optimizations, and improvements across multiple filters. Our goal is to provide fast, scriptable, and highly customizable image processing tools that work for photographers, digital artists, and researchers alike.

Would love to hear your thoughts and feedback! You can check it out here: https://gmic.eu. Happy to answer any questions!
