The method I used to estimate the depthmap (consistent in time!) comes from this brilliant paper :(CVPR2025).

Turn any video into a 3D hologram ✨.Excited to share a working prototype that explores this, making standard videos feel more organic in WebXR. By leveraging video depth data, we can bring them to life as interactive particle clouds. Demo: #XR

Enhanced my Tennis Viz for Roland Garros! With live player distance tracking, a top-view heatmap, and speed-dependent motion blur. I should run it for a complete game. I wonder how many kilometers they run in a Game?! 🎾

Ever fascinated by Depth Estimation and 3D reconstruction from a single image, I just tested the newly released PSHUMAN paper using the image on the left. Truly impressive results, Congrats on the amazing work! πŸ”₯@YuanLiu41955461
