Claim 0:
1. A computer-implemented method of relighting an input image, the method comprising:
receiving a single input image having an illuminated subject; and
relighting the single input image by inputting the single input image and a target spherical harmonic illumination embedding to an autoencoder of a neural network to generate a relighted image having the illuminated subject of the single input image illuminated based on the target spherical harmonic illumination embedding, the autoencoder having an encoder and a decoder that are trained using a spherical harmonic loss function;
wherein relighting the single input image comprises:
generating, by the encoder, an input content embedding that represents the subject of the input image;
generating, by the decoder, the relighted image using the input content embedding and the target spherical harmonic illumination embedding as inputs to the decoder.
