Abstract: Most garments are designed according to the standard scale of mannequin. However, for customers with non-standard body shape, it is hard to match them with garments of standard size. Based on the above background, we have proposed a body shape-oriented garment style transfer method. Firstly, for a number of garments of different styles, physically-based simulation method is used to wear the garments on standard human model and the non-standard human model. The garment instances fitting for standard body shapes and non-standard body shapes, are then constructed. Secondly, affine transformation is used to represent deformation between the same garment instances under the standard body shape and non-standard body shape, and the cloth deformation is computed using principal component analysis so that the cloth deformation caused by body shape can be retained and the cloth deformation caused by the garment style can be removed. Finally, cloth deformation is used to transfer the garment style from standard to non-standard model, and we use average discrete curvature to measure the degree of change in clothing style before and after garment transfer. The experiment results show that the transferred garments have the style information of the garment under standard body shape and the body characteristics of the garment under non-standard body shape.
