An open-source C++ library for CNN-based face detection in images, with the model embedded as static C source so it has no external dependencies. It uses SIMD optimizations (AVX2, NEON) to achieve very high detection speeds, up to thousands of FPS on small images.

Use cases

• detect faces in images
• real-time face detection from camera feed
• embed face detection in a C++ application
• run face detection on ARM devices
• fast face detection without external dependencies

When to choose

• you need fast, dependency-free face detection in C/C++
• you target embedded or ARM platforms with NEON support
• you want a model compiled directly into your binary

When to avoid

• you need face recognition or landmarks beyond detection
• you prefer a Python-first or GPU-accelerated deep learning stack
• you need dynamic input shapes with OpenCV DNN
