In its entirety, the dataset provides now 65 million images from over 15 hours of diverse human facial expression performances. We improved the color consistency of the recorded images with a better color calibration procedure. As a result, 3D reconstructions with images from the NeRSemble dataset should become better and look more realistic. Finally, we made it much easier to download the recordings with our new download repository. It now just takes a single command to download all frontal hair shake videos of all participants or to download all recordings of a single participant. Check it out: Awesome work by @TobiasKirschst1 @SGiebenhain !!!

With DeepSeek, opinions are shifting from "winning in AI needs infinite compute" to "all cutting-edge models are cheap and free". It's somewhat obvious that brute-force compute was a bad idea, while at the same time, training big models still takes significant resources.

@angelaqdai @chandan__yes @liuyuehcheng Amazing effort by @chandan__yes and @liuyuehcheng! ScanNet++ has been one of our most labor-intense research projects. We are also planning an exciting update regarding the NVS and semantic benchmarks; i.e., we'll make it easier to submit and evaluate :)
