Abstract: The present invention relates to a method for deriving a 3D data from image data comprising: receiving, from at least one camera, image data representing an environment; detecting, from the image data, at least one object within the environment; classifying the at least one detected object, wherein the method comprises, for each classified object of the classified at least one objects: determining a 2D skeleton of the classified object by implementing a neural network to identify features of the classified object in the image data corresponding to the classified object; and constructing a 3D skeleton for the classified object, comprising mapping the determined 2D skeleton to 3D.

Abstract: The invention relates to a method of inserting an insertion object into a sequence of images. The insertion object may be an image, a video, or a three-dimensional model, which could possibly be animated. Particularly, but not exclusively, the invention relates to the insertion of advertisement images into video, such as videos of sporting events.

Abstract: A computer system and method are proposed for solving physical problems governed by Poisson or Helmholtz equations. Values of at least one unknown physical quantity at points are determined using known values of at least one second physical quantity. The points are clustered into a hierarchical skeleton structure using a clustering algorithm based on distances between the points. Interactions between distant clusters are approximated, to give a system of equations which can be solved more efficiently.
