@AlphaQi as I know, mtcnn in cpu is slow, how do you speed it up?

AlphaQi commented 7 years ago

I am so sorry , I didn't speed it up , I just use openblas for the conv part If you want to speed it up, I advice 1,you can change the nms_thread 2,use openmp 3,improve algorithm, for example, you can design smaller cnn

the speed is 80ms with the 4.jpg, and 4 faces. clock时间 不要除以，你除以之后导致时间错了10倍；

where we can change the nms_thread in the code ? number of thread/core
