Real-time Performance #60

Closed technicalReport closed 7 years ago

technicalReport commented 7 years ago

Issue summary

I have some question about its real time speed. I have run it with some dataset, but its performance is not fast enough to be 'real time'.

Question I test the openpose with Tesla K80 by using the zhenduoyan.avi dataset. But it can only be up to 0.6 fps, which is much smaller than 8fps as the author mentioned in his paper. Any comments or suggestions on this point?

Check https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/installation.md#faq In particular, the Q: Low speed question. Post again if you have any further question about it (and please also post your hardware if you post again, so we can better answer). Thanks

Thanks for your kindly reply. Now I try it with the command ' ./build/examples/openpose/openpose.bin --video ../zhenduoyan.mp4 --net_resolution 320x176 --model_pose MPI_4_layers --process_real_time --num_gpu 4' , the average fps turns to be 1.6, which is still much slower than the result mentioned in the paper. BTW: I test it in the remote linux server and the output video sends back via xming.

If you are sending back the output video the speed is highly conditioned by that. Try without any visual output (--no_render_pose) to see the real speed. EDITED: closed for now. Please post again if you have any other related question.
