 This is an open source library for CNN-based face detection in images. The CNN model has been converted to stastic variales in C source files. The source code does not depend on any other libraries. What you need is just a C++ compiler. You can compile the source code under Windows, Linux, ARM and any platform with a C++ compiler.
 
-SIMD instructions are used to speedup the detection. If you use Intel CPU, you can enable AVX2 and NEON for ARM.
