Classification: CPC G | IPC G

Claim 8:
9. A system, comprising:
one or more processors; and
one or more non-transitory program storage devices comprising computer readable instructions executable by the one or more processors to:
obtain a neural network configured to decompose images into a plurality of lighting-related components, wherein the neural network is trained on real and synthetic images using one or more self-supervision terms, wherein at least one of the one or more self-supervision terms comprises a cross-relighting loss term, and wherein the cross-relighting loss term comprises computing a difference between: (1) a first image that is relit with estimated lighting for a second image; and (2) the second image;
obtain an input image;
use the neural network to decompose the input image into the plurality of lighting-related components;
estimate lighting information for the input image based, at least in part, on the plurality of lighting-related components; and
render a reconstructed version of the input image based, at least in part, on the input image, the estimated lighting information, and the plurality of lighting-related components.
