Snap has released a new model for animating the entire human body (not just the face). Looks pretty good.
The principle is similar to their previous method - First order motion model for animation of heads. The difference is that (a) the background motion is explicitly modeled here; and (b) instead of regressing local affine transformations for a set of keypoints, this method learns to find heatmaps of different body parts in unsupervised way and the transformation matrix of each body part is computed by applying principal component analysis (PCA) to the predicted heatmaps.
P.S. 2 years ago another method for animating the whole body "Everybody Dance Now" was released, but there you had to retrain the network for each new person.

As such, the SC would like to remind investors to always exercise caution when evaluating investment opportunities, especially those promising unrealistically high returns with little or no risk. Investors should also never deposit money into someone’s personal bank account if instructed. For Oleksandra Tsekhanovska, head of the Hybrid Warfare Analytical Group at the Kyiv-based Ukraine Crisis Media Center, the effects are both near- and far-reaching. Asked about its stance on disinformation, Telegram spokesperson Remi Vaughn told AFP: "As noted by our CEO, the sheer volume of information being shared on channels makes it extremely difficult to verify, so it's important that users double-check what they read." There was another possible development: Reuters also reported that Ukraine said that Belarus could soon join the invasion of Ukraine. However, the AFP, citing a Pentagon official, said the U.S. hasn’t yet seen evidence that Belarusian troops are in Ukraine. Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp.
