Abstract
A system and method of training an appearance signature extractor using a training data set, the training data set including input images associated with a plurality of domains. The method comprises inputting an input image of the training data set, an identity label, and a domain label to the appearance signature extractor, the identity label providing identity information of the input image, and the domain label providing domain information of the input image, the domain information corresponding to one of the domains; determining an appearance signature from the input image using the appearance signature extractor; determining an identity score from the appearance signature; determining a loss value between the identity score and the identity label according to the domain label, wherein the loss value relates to an error between the identity score and the identity label; and updating the appearance signature extractor using the determined loss value.
