Modern Image Processing Algorithms Implementation in C
It looks promising.
I like the way each algorithm is explained with minimal example and demo images.
I'm looking for such a lightweight vision lib to embed simple image manipulation programs on tiny ESP32-CAM boards.
OpenCV seems too heavy to integrate on such small devices.
So far, I've been able to develop simple image processing programs with CImg[1] (simple filtering, image cropping, adding text).
I'll try to spend some time exploring this SOD lib, thank you for sharing.
