< Back Neural Radiance Fields For Outdoor Scene Relighting Photorealistic editing of outdoor scenes from photographs requires a profound understanding of the image formation process and an accurate estimation of the scene geometry, reflectance and illumination. The technique allows simultaneous editing of both scene illumination and camera viewpoint using only a collection of outdoor photos shot in uncontrolled settings. European Conference on Computer Vision (ECCV) 2022 6 Jan 2024 Abstract Photorealistic editing of outdoor scenes from photographs requires a profound understanding of the image formation process and an accurate estimation of the scene geometry, reflectance and illumination. A delicate manipulation of the lighting can then be performed while keeping the scene albedo and geometry unaltered. We present NeRF-OSR, i.e., the first approach for outdoor scene relighting based on neural radiance fields. In contrast to the prior art, our technique allows simultaneous editing of both scene illumination and camera viewpoint using only a collection of outdoor photos shot in uncontrolled settings. Moreover, it enables direct control over the scene illumination, as defined through a spherical harmonics model. It also includes a dedicated network for shadow reproduction, which is crucial for high-quality outdoor scene relighting. To evaluate the proposed method, we collect a new benchmark dataset of several outdoor sites, where each site is photographed from multiple viewpoints and at different timings. For each timing, a 360° environment map is captured together with a colour-calibration chequerboard to allow accurate numerical evaluations on real data against ground truth. Comparisons against state of the art show that NeRF-OSR enables controllable light and viewpoint editing at higher quality and with realistic self-shadowing reproduction. Our method and the dataset are publicly available in the Downloads section below. https://4dqv.mpi-inf.mpg.de/NeRF-OSR/ For more: Design, AI, NeRF, Machine Learning, Neural Network, 3D Visualisation Previous Next

< Back Quantum Computing’s Hard, Cold Reality Check Hype is everywhere, skeptics say, and practical applications are still far away IEEE Spectrum 22 Dec 2023 The quantum computer revolution may be further off and more limited than many have been led to believe. That’s the message coming from a small but vocal set of prominent skeptics in and around the emerging quantum computing industry. Quantum computers have been touted as a solution to a wide range of problems, including financial modeling, optimizing logistics, and accelerating machine learning. Some of the more ambitious timelines proposed by quantum computing companies have suggested these machines could be impacting real-world problems in just a handful of years. But there’s growing pushback against what many see as unrealistic expectations for the technology. https://spectrum.ieee.org/quantum-computing-skeptics For more: Machine Learning, Security, Protocols, AI, Algorithm, Quantum Previous Next
