Abstract
A hierarchical data structure has sets of nodes representing a 3D space of an environment at different granularity levels. Sets of neural networks at different granularity levels are trained. For a portion of an output image, a granularity level at which the portion is to be reconstructed is determined. A corresponding node is identified; the node having sets of child nodes. A set of child nodes is selected at the granularity level at which the portion is to be reconstructed. For a child node, a cascade of neural networks is utilised to reconstruct the portion. Granularity level of N+1neural network is higher than that of Nneural network. Input of a neural network includes outputs of at least a predefined number of previous neural networks.
