A casual work about retainining mtcnn Pnet and Onet. make it a little bit fast,which achiciving 100fps+ (1920*1080 minSize 60) at intel i7 6700k (st),but the accuracy is not so well.

• OpenCV 3.4.1 only

The demo base on OpenCV DNN module. my computer with Intel i7 6700k (st) can achicive 100fps+ (1920*1080 minSize 60)compiled with OpenBLAS (OpenCV 3.4.1) ,if you wanna achieve the better performance.you can compile with Intel MKL-DNN Inference Engine package to accelerate.

• Optimize PNet Rnet Onet with modern net desigin (bottleneck , depthwise conv ,inverted residual block...) .
• Benchmark on FDDB.
• Computing sharing to accelerate speed when the detected faces increased.
