Publication number: 20240037829Abstract: To compute an image of a dynamic 3D scene comprising a 3D object, a description of a deformation of the 3D object is received, the description comprising a cage of primitive 3D elements and associated animation data from a physics engine or an articulated object model. For a pixel of the image the method computes a ray from a virtual camera through the pixel into the cage animated according to the animation data and computes a plurality of samples on the ray. Each sample is a 3D position and view direction in one of the 3D elements. The method computes a transformation of the samples into a canonical cage. For each transformed sample, the method queries a learnt radiance field parameterization of the 3D scene to obtain a color value and an opacity value. A volume rendering method is applied to the color and opacity values producing a pixel value of the image.Type: ApplicationFiled: September 19, 2022Publication date: February 1, 2024Inventors: Julien Pascal Christophe VALENTIN, Virginia ESTELLERS CASAS, Shideh REZAEIFAR, Jingjing SHEN, Stanislaw Kacper SZYMANOWICZ, Stephan Joachim GARBIN, Marek Adam KOWALSKI, Matthew Alastair JOHNSON

Publication number: 20230326238Abstract: A neural optimizer is disclosed that is easily applicable to different fitting problems, can run at interactive rates without requiring significant efforts, does not require hand crafted priors, carries over information about previous iterations of the solve, controls the learning rate of each parameter independently for robustness and convergence speed, and combines updates from gradient descent and from a method capable of very quickly reducing the fitting energy. A neural fitter estimates the values of the parameters ? by iteratively updating an initial estimate ?0.Type: ApplicationFiled: April 12, 2022Publication date: October 12, 2023Inventors: Julien Pascal Christophe VALENTIN, Federica BOGO, Vasileios CHOUTAS, Jingjing SHEN

Publication number: 20230316552Abstract: The techniques described herein disclose a system that is configured to detect and track the three-dimensional pose of an object (e.g., a head-mounted display device) in a color image using an accessible three-dimensional model of the object. The system uses the three-dimensional pose of the object to repair pixel depth values associated with a region (e.g., a surface) of the object that is composed of material that absorbs light emitted by a time-of-flight depth sensor to determine depth. Consequently, a color-depth image (e.g., a Red-Green-Blue-Depth image or RGB-D image) can be produced that does not include dark holes on and around the region of the object that is composed of material that absorbs light emitted by the time-of-flight depth sensor.Type: ApplicationFiled: April 4, 2022Publication date: October 5, 2023Inventors: JingJing SHEN, Erroll William WOOD, Toby SHARP, Ivan RAZUMENIC, Tadas BALTRUSAITIS, Julien Pascal Christophe VALENTIN, Predrag JOVANOVIC
