Collecting The Puzzle Pieces: Disentangled Self-Driven Human Pose Transfer by Permuting Textures
share
Human pose transfer aims to synthesize a new view of a person under a given pose. Recent works achieve this via self-reconstruction, which disentangles pose and texture features from the person image, then combines the two features to reconstruct the person. Such feature-level disentanglement is a difficult and ill-defined problem that could lead to loss of details and unwanted artifacts. In this paper, we propose a self-driven human pose transfer method that permutes the textures at random, then reconstructs the image with a dual branch attention to achieve image-level disentanglement and detail-preserving texture transfer. We find that compared with feature-level disentanglement, image-level disentanglement is more controllable and reliable. Furthermore, we introduce a dual kernel encoder that gives different sizes of receptive fields in order to reduce the noise caused by permutation and thus recover clothing details while aligning pose and textures. Extensive experiments on DeepFashion and Market-1501 shows that our model improves the quality of generated images in terms of FID, LPIPS and SSIM over other self-driven methods, and even outperforming some fully-supervised methods. A user study also shows that among self-driven approaches, images generated by our method are preferred in 72 cases over prior work.
