Yolov4

[refigh]

Yolov4 was released. it is good if you have a performance comparison with v3.

I haven't measured the performance yet, but I'm always ready to verify it. I will measure it when I have time to work on it. By the way, I measured the performance in an environment other than OpenVINO, but I couldn't see any dramatic performance improvement.

on CPU, with OpenVino, I compared them. for same resolution, run-time is almost twice slower, but detection precision was not so much higher, but was a bit higher in some cases.
on NCS2 I did not check them yet, since I can't find FP16 model of yolov4 yet.
