We demonstrate how those learned features can boost the performance of self-supervised action recognition, and can be used for video retrieval. Importantly, we show that through predicting the speed of videos, the model learns a powerful and meaningful space-time representation that goes beyond simple motion cues. We demonstrate prediction results by SpeedNet on a wide range of videos containing complex natural motions, and examine the visual cues it utilizes for making those predictions. We show how this single, binary classification network can be used to detect arbitrary rates of speediness of objects. SpeedNet is trained on a large corpus of natural videos in a self-supervised manner, without requiring any manual annotations. The core component in our approach is SpeedNet-a novel deep network trained to detect if a video is playing at normal rate, or if it is sped up. We wish to automatically predict the "speediness" of moving objects in videos-whether they move faster, at, or slower than their "natural" speed. Furthermore, we also apply SpeedNet for generating time-varying, adaptive video speedups, which can allow viewers to watch videos faster, but with less of the jittery, unnatural motions typical to videos that are sped up uniformly. Sounds like someone wheezing and whistling in the corner, which is quite annoying as the Pis are in my home office so I'm hearing this all the time.1 code implementation in PyTorch. As the temperature seems to hover around 50C most of the time, the fans come on a lot, sometimes for just a half second at a time. One (possibly both) of the Pis has started intermittently making that high pitched noise on and off, possibly in association with the fan being triggered frequently due to the settings not working. I've done a bit of checking, turning one off at a time, and they both appear to be doing the same thing with the fans after the same software updates today. It seems that the fans now come on when the temperature hits 50C - which if I think is maybe the default if not overridden? Since then, both of the Pis appear to have stopped controlling the fan according to the above settings. I did that today as usual and there were a few updates installed. I ssh in and run apt update/upgrade a couple of times a week. (I've everything updated to the last version)Ĭode: Select all # to regulate when the fan comes on and offĭtparam=poe_fan_temp0=60000,poe_fan_temp1=65000 Or there is an alternative way to do this since september with this thread was published -? need to ^c, as not coming back to the prompt Ignored it, done a chmod +x and copied over to /boot/overlay (backed up first).Īnd sudo dmesg -w, doesn't provide anything.
