Abstract: It is provided a computer-implemented method for creating a surface from a plurality of 3D curves. The method comprises providing a plurality of 3D curves, determining crossings between pairs of the curves, defining a base graph comprising nodes representing the crossings and arcs connecting pairs of nodes representing crossings that are neighbors, determining, from the graph, a mesh comprising vertices defined by a 3D position and edges connecting pairs of the vertices, and fitting the mesh with a surface. Such a method makes the creation of a surface from a plurality of 3D curves easier.
Abstract translation: 提供了一种用于从多个3D曲线创建表面的计算机实现的方法。 该方法包括提供多个3D曲线，确定曲线对之间的交叉，定义包括表示交叉点的节点的基本图形，以及连接表示作为相邻交叉点的节点对的弧，从图中确定包括定义的顶点的网格 通过3D位置和连接顶点对的边缘，并将网格与表面相配合。 这种方法使得从多个3D曲线创建表面更容易。

Abstract: A computer-implemented method of computer vision in a scene that includes one or more transparent objects and/or one or more reflecting objects comprises obtaining a plurality of images of the scene, each image corresponding to a respective acquisition of a physical signal, the plurality of images including at least two images corresponding to different physical signals; and generating a segmented image of the scene based on the plurality of images. This improves the field of computer vision.
