GramGAN: Deep 3D Texture Synthesis From 2D Exemplars

NeurIPS 2020poster

We present a novel texture synthesis framework, enabling the generation of infinite, high-quality 3D textures given a 2D exemplar image. Inspired by recent advances in natural texture synthesis, we train deep neural models to generate textures by non-linearly combining learned noise frequencies. To…

Challenges in Disentangling Independent Factors of Variation

ICLR 2018workshop

We study the problem of building models that disentangle independent factors of variation. Such models encode features that can efficiently be used for classification and to transfer attributes between different images in image synthesis. As data we use a weakly labeled training set, where labels in…

Disentangling Factors of Variation by Mixing Them

CVPR 2018poster

We propose an approach to learn image representations that consist of disentangled factors of variation without exploiting any manual labeling or data domain knowledge. A factor of variation corresponds to an image attribute that can be discerned consistently across a set of images, such as the pose…

Specular-to-Diffuse Translation for Multi-View Reconstruction

ECCV 2018poster

Most multi-view 3D reconstruction algorithms, especially when shape-from-shading cues are used, assume that object appearance is predominantly diffuse. To alleviate this restriction, we introduce S2Dnet, a generative adversarial network for transferring multiple views of objects with specular reflec…

Understanding Degeneracies and Ambiguities in Attribute Transfer

ECCV 2018poster

We study the problem of building models that can transfer selected attributes from one image to another without affecting the other attributes. Towards this goal, we develop analysis and a training methodology for autoencoding models, whose encoded features aim to disentangle attributes. These featu…
