FlyCV

Why we included this project

FlyCV is a C/C++ image processing library tuned for ARM, where it runs common operators noticeably faster than OpenCV while keeping the compiled binary small. Its API deliberately mirrors OpenCV, so moving an existing pipeline over is mostly swapping includes and recompiling, and the project ships migration guidance plus build scripts for Android, armlinux, iOS, Windows, and macOS. Fine-grained compile flags let you build only the operators you actually use, which matters when binary size is tight, and a custom-namespace option avoids clashes if your app already links another image library. For teams doing vision preprocessing on phones or embedded Linux boards, that combination of speed and a small footprint is the main reason to try it.
