libmpix is a lightweight open-source library that brings common imaging operations—like pixel format conversion, debayering, blurring, sharpening, resizing, and color correction—to microcontrollers. It’s designed to reduce memory overhead and has Zephyr support out-of-the-box 🪁. In this new Zephyr Tech Talk episode, Benjamin Cabé will be joined by Josuah Demangeon, co-maintainer of the Video subsystem in Zephyr and author of libmpix, to discuss video support in Zephyr and how to add libmpix to the mix for advanced image processing.
Zephyr Tech Talks are live streams organized by and for the Zephyr community. Join us live to ask your questions directly to our guests, or catch the recording anytime afterward.
