Google today released a demo app that visualizes a real-time point cloud from uDepth, the stereo depth sensor built into the Pixel 4 and Pixel 4 XL. As the tech giant explains in a lengthy post, uDepth taps machine learning to identify users while protecting against spoof attacks; it supports a number of features, including post-processing photo retouching and depth-based scene segmentation as…

In an academic paper published this week on the preprint server Arxiv.org, a team of researchers from Princeton, Microsoft, the nonprofit Algorand Foundation, and Technion propose Falcon, an end-to-end framework for secure computation of AI models on distributed systems. They claim that it’s the first secure C++ framework to support high-capacity AI models and batch normalization, a technique…
