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.
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.
