    DispVoxNets: Non-Rigid Point Set Alignment with Supervised Learning Proxies.
    S. Shimada, V. Golyanik, E. Tretschk, D. Stricker and C. Theobalt.
    In International Conference on 3D Vision (3DV), 2019; Oral

    We introduce a supervised-learning framework for nonrigid point set alignment of a new kind — Displacements on Voxels Networks (DispVoxNets) — which abstracts away from the point set representation and regresses 3D displacement fields on regularly sampled proxy 3D voxel grids. Thanks to recently released collections of deformable objects with known intra-state correspondences, DispVoxNets learn a deformation model and further priors (e.g., weak point topology preservation) for different object categoriessuch as cloths, human bodies and faces.

    IsMo-GAN: Adversarial Learning for Monocular Non-Rigid 3D Reconstruction.
    S. Shimada, V. Golyanik, C. Theobalt and D. Stricker.
    In Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2019; Oral

    The majority of the existing methods for non-rigid 3D surface regression from a single 2D image require an object template or point tracks over multiple frames as an input, and are still far from real-time processing rates. In this work, we present the Isometry-Aware Monocular Generative Adversarial Network (IsMo-GAN) — an approach for direct 3D reconstruction from a single image, trained for the deformation model in an adversarial manner on a light-weight synthetic dataset.

    HDM-Net: Monocular Non-Rigid 3D Reconstruction with Learned Deformation Model.
    V. Golyanik, S. Shimada, K. Varanasi and D. Stricker.
    In International Conference on Virtual Reality and Augmented Reality (EuroVR) 2018; Oral (Long Paper)

    Monocular dense 3D reconstruction of deformable objects is a hard ill-posed problem in computer vision.In this work, we propose a new hybrid approach for monocular non-rigid reconstruction which we call Hybrid Deformation Model Network (HDM-Net). In our approach, a deformation model is learned by a deep neural network, with a combination of domainspecific loss functions.
