Patent number: 10572770Abstract: To address the needs of applications that work with large-scale unstructured point clouds and other noisy data (e.g. image and video data), tangent convolution of 3D data represents 3D data as tangent planes. Tangent convolution estimates tangent planes for each 3D data point in one or more channels of 3D data. Tangent convolution further computes the tangent image signals for the estimated tangent planes. Tangent convolution precomputes the tangent planes and tangent image signals to enable convolution to be performed with greater efficiency and better performance than can be achieved with other 3D data representations.Type: GrantFiled: June 15, 2018Date of Patent: February 25, 2020Assignee: Intel CorporationInventors: Jaesik Park, Vladlen Koltun, Maxim Tatarchenko, Qian-Yi Zhou
