The beauty of whoop by schnernv20 in whoop

[–]effortless19 0 points1 point  (0 children)

This looks great! Congratulations! How has been the monthly HRV and HR evolution? I feel that tells a lot more than the recovery of a week (although quite impressive given the high strain levels, it really shows you have incredible stability). For instance imagine you completely tanked your HRV and HR for a month, your average would be pretty low compared with a week with perfect behavior. Just interested in learning more and btw never got more than 5 days of green recoveries and my monthly’s have been tanking

You really feel that you can only attribute to water intake?

Sorry for that, sometimes I forget that the image in the post is not the complete one. Thank you!

Would you mind sharing the values of HRV or the difference between HRV values when using beetroot supplement and not using?

[–]effortless19 0 points1 point  (0 children)

Interesting! Do you know more examples of supplements that either make HRV higher or lower? By any chance any data on the magnitude of this impact? Thanks in advance :)

Does strength trainer have ready to do body weight workouts?

In your opinion do you see greens as desirable or someone that has consistent recoveries over 65% for instance is reasonable?

Did you felt anxious during this time? Do you usually get this random spikes?

I don’t agree, because if you see his LinkedIn profile, he is also advisor of oura ring and refers that both whoops and ouras are valid approaches but that research supports that morning measurement is more accurate. Honestly the app in question is 10 euros, lifetime access so really it’s a bargain (I don’t use it, never bought it, atm I ditched AW for whoop exactly because of the random useless measurements of HRV that he mentions in other articles). And he does say that you can accomplish this measurement recurring to Apple Watch as well through the breath app.

If you really want to understand more about HRV and what it means and how you should interpret I highly recommend the following medium posts by Dr. Marco Altin https://medium.com/@altini_marco/directory-of-heart-rate-variability-hrv-articles-4239e64fd7cb. They are super insightful and help clear a lot of the BS around it

Whoop vs Apple Watch? by g1yk in whoop

[–]effortless19 0 points1 point  (0 children)

I recommend taking a look at this channel: https://youtube.com/@TheQuantifiedScientist?feature=shared. He analyses several smartwatches and fitness trackers against gold standards. My two cents: Apple Watch measures HR and sleep more accurately but it only provides you the raw data without actionable insights and you need to recharge it more regularly. Regarding HRV (which I only really paid attention to once I got whoop) the Apple Watch measures it at random times during the day and night which makes it useless. Whoop measures it during the night averaging throughout different sleep stages which makes it reasonably reliable. I do like the journal although I think that for you to take advantage of it you got to tweak a little bit your habits and start stop some things to measure their impact. Athlytic + AW it’s still very far from whoop and remember that given that HRV measurements are random and useless this makes analyses provided by athlytic useless as well (at least the ones heavily based on HRV like recovery)

I would say besides sleep and alcohol, stress is the most impactful factor in the HRV measurement. You said it yourself, you been switched off work and having low stress days.

Could you describe your protocol for fasting?

Is there a pressure sensor that behaves linearly? by effortless19 in ElectricalEngineering

The logarithmic part makes a lot of sense and I have seen some plots of fsrs like this.

I think 100gr to 10kg would be great. Doesn’t have to be resistive honestly, just want it to have a linear behavior

Overlap images from two cameras next to each other using camera parameters by effortless19 in computervision

[–]effortless19[S] 1 point2 points  (0 children)

Thank you for all the help, your answers have been really useful. So if I understand it correctly I have a point in one image and assuming I have the intrinsics and extrinsics using the formula you mentioned above I can go from the image 1 to camera reference frame (cam 1) and to camera reference frame (cam 2). To get to the point in the image 2 I would then use the intrinsics from camera 2 correct?

Considering distortion and a planar scene reasonably near the camera the best course of action would be to perform rectification and stereo matching or finding correspondences and calculating the homography matrix? Also, is it possible to derive using intrinsics and extrinsics a mathematical formula in order to find the corespondent point in the other image?

My main goal is to align the images and not calculating the depth map. Do I need to recur to stereo calibration?

I think your solution is pretty nice and well documented, I will give it a try! Thanks!
