 #### With AlphaPose:
-[AlphaPose](https://github.com/MVIG-SJTU/AlphaPose) is slightly less renowned than OpenPose and not as easy to run on non-Linux machines, but its accuracy is comparable. As a top-down approach (unlike OpenPose which is bottom-up), it is faster on single-person detection, but slower on multi-person detection.
