Method for transfer of a style of a reference visual object to another visual object, and corresponding electronic device, computer readable program products and computer readable storage medium

An electronic device comprising at least one memory and one or several processors configured for collectively transferring a style of a reference visual object to an input visual object, wherein said one or several processors are configured for collectively:

• finding a correspondence map ϕ assigning to at least one pixel x in the input visual objet a corresponding pixel ϕ(x) in the reference visual object, said finding of a correspondence map ϕ comprising:
• quadtree splitting of said input visual object (I) into a plurality of regions Ri, delivering, for at least one region Ri, a set of K candidate labels Li, representing region correspondences between said input visual object (I) and said reference visual object (E);
• and
• obtaining a reduced set of K candidate labels AL by using an inference model of Markov Random fields (MRF) type, wherein said MRF inference model is solved by approximating a Maximum a Posteriori using a loopy belief propagation type method, delivering the approximate marginal probabilities for at least one variable of the MRF model.
