Abstract: In some embodiments, a computer-implemented method of rendering reference makeup on an input image is provided. A computing system obtains a tensor of neural descriptors that represent attributes of the reference makeup generated by an attribute extractor from a reference image showing the reference makeup. The computing system uses a renderer to generate at least one rendered image based on the input image and the tensor of neural descriptors. The computing system provides the at least one rendered image for display on a display device.

Abstract: According to one aspect, what is proposed is a method for generating a photorealistic rendering of a cosmetic product, comprising: —obtaining (10, 12) a reference image (Xref) of a real cosmetic product (PC) applied to a first person (P1) and at least one source image (Xjsource) of a second person (P2), —implementing (13) an encoding artificial neural network (E) configured to determine characterizing parameters (E(Xref)) of the cosmetic product (PC) from the reference image (Xref), and then —implementing (14) a realistic physically based rendering engine (R) configured to generate a transformed image (R (Xjsource, E(Xref))) in which a photorealistic rendering of the cosmetic product (PC) is applied to the person (P2) from said at least one source image (Xjsource) based on the characterizing parameters (E (Xref)) of the cosmetic product (PC) that are determined by the encoding artificial neural network (E).
