Original Abstract Submitted

The training apparatus includes an angle difference computation section which calculates a difference between angles estimated by one or more angle estimators, a rigid transformation section which transforms the feature of the input image according to the difference, a matching loss computation section which calculates a matching loss between a non-transformed feature extracted by the one or more feature extractors and the feature transformed by the rigid transformation section, and an updating section which updates at least the one or more angle estimators with reference to the matching loss, wherein the rigid transformation section transforms the feature in a way that the feature appears as if it has been extracted from an image at the same angle of the image from which the non-transformed feature value has been extracted.
