Prior work for articulated 3D shape reconstruction often relies on specialized sensors (e.g., synchronized multi-camera systems), or pre-built 3D deformable models (e.g., SMAL or SMPL). Such methods are not able to scale to diverse sets of objects in the wild. We present BANMo, a method that requires neither a specialized sensor nor a pre-defined template shape. BANMo builds high-fidelity, articulated 3D “models” (including shape and animatable skinning weights) from many monocular casual videos in a differentiable rendering framework. While the use of many videos provides more coverage of camera views and object articulations, they introduce significant challenges in establishing correspondence across scenes with different backgrounds, illumination conditions, etc. Our key insight is to merge three schools of thought; (1) classic deformable shape models that make use of articulated bones and blend skinning, (2) volumetric neural radiance fields (NeRFs) that are amenable to gradient-based optimization, and (3) canonical embeddings that generate correspondences between pixels and an articulated model. Ukrainian President Volodymyr Zelenskyy made a brief national address to say that he was declaring martial law and that Ukraine would “win”. “Putin has just launched a full-scale invasion of Ukraine,” Ukraine’s Foreign Minister Dmytro Kuleba wrote on Twitter. “Peaceful Ukrainian cities are under strikes. This is a war of aggression. Ukraine will defend itself and will win. The world can. Must stop Putin. US President Joe Biden, in a phone call with Zelenskyy, condemned the “unprovoked and unjustified attack by Russian military forces”, the White House said. Biden said in a statement he briefed Zelenskyy on Washington’s and its allies’ planned next steps against Russia, including “severe sanctions”. In an impassioned appeal, UN chief Antonio Guterres condemned Russia’s actions. “In the name of humanity, bring your troops back to Russia,” he said. NATO called an emergency meeting with chief Jens Stoltenberg condemning what he said was a “reckless attack”. Russia’s UN ambassador Vasily Nebenzya, who is the current president of the Security Council, admitted to fellow members of the council that “special operations” were under way, insisting to the other ambassadors that the action did not amount to war and was a consequence of Ukraine’s actions. just war theory
