Baller Obrienslalom Posted March 13, 2020 Baller Share Posted March 13, 2020 A couple of years ago, I looked at predicting human poses from an image and/or video. It turned out to be more effort than I was willing to put in at the time (especially for water skiing, since there is a lot of noise and occlusion via ropes and spray). Anyway, it led me to follow a few people's work in the space, specifically Michael Black's work: https://github.com/mkocabas/VIBE I ran his latest project on a clip from the 'Terry Winter at Quarter Speed' video from Horton's channel. Out of the box, this performed amazing well. Also, there isn't any specific training towards this type of movement. Very promising in my opinion. I also tested it against some random clips from youtube, but I won't subject randoms to this discussion. Since this is in quarter speed, and very well zoomed in, I assumed it would be much better. Honestly, it's better in some areas, but much more jittery for some reason. Here is the result: You can find a ton of work in various sports doing this sort of thing. From the tracked joint data you can do a lot of automated analysis or comparisons between runs. It's also interesting to see the 3D pose, since we rarely get that view in this sport. Thoughts?

Baller aupatking Posted March 13, 2020 Baller Share Posted March 13, 2020 I want to make jokes about it, but when you slow it down even further, it really does look like there’s potential there. I’m sure with time spent teaching it to recognize the position of the feet is (fairly) static, and ironing some other little quirks out, there’s decent data. If you were able to run this with enough video, I wonder if you could factually establish what is truly the most important fundamentals? Basically score the skier Link to comment Share on other sites More sharing options...
Baller jimbrake Posted March 13, 2020 Baller Share Posted March 13, 2020 that was oddly disturbing to watch Link to comment Share on other sites More sharing options...
Baller jetpilotg4 Posted March 13, 2020 Baller Share Posted March 13, 2020 I agree with you @jimbrake Hate to see what I’d look like on it Frightening I’m sure Link to comment Share on other sites More sharing options...
Baller jpattigr Posted March 13, 2020 Baller Share Posted March 13, 2020 Would like to see Robert Pigozzi overlapped with his unique style! Link to comment Share on other sites More sharing options...
Baller Obrienslalom Posted March 13, 2020 Author Baller Share Posted March 13, 2020 Hahah, well I'm glad I put minimal effort into working on something. Didn't know everyone would be creeped out by it! Link to comment Share on other sites More sharing options...
klindy Posted March 13, 2020 Share Posted March 13, 2020 That's fascinating. The potential for coaching, judging, even ski design could be huge. Link to comment Share on other sites More sharing options...
Tevskis Posted March 13, 2020 Share Posted March 13, 2020 I LOVE this!!! I also started laughing ridiculously hard this morning when I first saw this! I see in this a near perfect representation of why top short-line skiers run exponentially more buoys than the masses. Makes me smile hearing Terry say "if you don't feel like you're going to eat s@$% at any time you're probably not doing it right" Following just the 3D figure, his mass dang near throws him out the front after loading through the gates. Yet in the video, Still, Tall and early into the buoy-line.... Perfection :) Link to comment Share on other sites More sharing options...
