TL;DR: Pixel-aligned Implicit Function (PIFu) as mentioned in this paper aligns pixels of 2D images with the global context of their corresponding 3D object to produce highresolution surfaces including largely unseen regions such as the back of a person.

TL;DR: This work proposes a multi-scale neural patch synthesis approach based on joint optimization of image content and texture constraints, which not only preserves contextual structures but also produces high-frequency details by matching and adapting patches with the most similar mid-layer feature correlations of a deep classification network.

TL;DR: Faces Learned with an Articulated Model and Expressions is low-dimensional but more expressive than the FaceWarehouse model and the Basel Face Model and is compared to these models by fitting them to static 3D scans and 4D sequences using the same optimization method.

TL;DR: A novel face tracking algorithm that combines geometry and texture registration with pre-recorded animation priors in a single optimization is introduced that demonstrates that compelling 3D facial dynamics can be reconstructed in realtime without the use of face markers, intrusive lighting, or complex scanning hardware.

TL;DR: This work proposes a truly differentiable rendering framework that is able to directly render colorized mesh using differentiable functions and back-propagate efficient supervision signals to mesh vertices and their attributes from various forms of image representations, including silhouette, shading and color images.
