Figure 1: We use statistics extracted from example faces to augment interactively drawn concept sketches for synthesizing realistic facial wrinkles. AbstractSynthesizing facial wrinkles has been tackled either by a long process of manual sculpting on 3D models, or using automatic methods that do not allow for user interaction or artistic expression. In this paper, we propose a method that accepts interactive sketchy drawings depicting wrinkle patterns, and synthesizes realistic looking wrinkles on faces. The method inherits the simplicity of sketching, making it possible for artists as well as novice users to generate realistic facial detail very efficiently, allowing fast preview for physical makeup, or aging simulations for fun and professional applications. All strokes are used to infer the wrinkles, retaining the expressiveness of the sketches and realism of the final result at the same time. This is achieved by designing novel multi-scale statistics tailored to the wrinkle geometry and coupled to the sketch interpretation method. The statistics capture the crosssectional profiles of wrinkles at different scales and parts of a face. The strokes are augmented with the statistics extracted from given example face models, and applied to an input face model interactively. The interface gives the user control over the shapes and scales of wrinkles via sketching while adding extra details required for realism automatically.

“…Other work looks specifically at wrinkles and folds of bending fingers [Venkataraman et al 2005]. Certainly, artist designed wrinkle maps (or normal maps) are likely the most common technique for modeling and rendering fine details since the early days [Blinn 1978], and are still widely used in current applications [Jimenez et al 2011]. In contrast to artist designed wrinkle maps or procedural models, data capture or precomputation can be used as a source of detailed surface geometry or maps.…”

EPFLFigure 1: Our system creates a fully rigged 3D avatar of the user from uncalibrated video input acquired with a cell-phone camera. The blendshape models of the reconstructed avatars are augmented with textures and dynamic detail maps, and can be animated in realtime. AbstractWe present a complete pipeline for creating fully rigged, personalized 3D facial avatars from hand-held video. Our system faithfully recovers facial expression dynamics of the user by adapting a blendshape template to an image sequence of recorded expressions using an optimization that integrates feature tracking, optical flow, and shape from shading. Fine-scale details such as wrinkles are captured separately in normal maps and ambient occlusion maps. From this user-and expression-specific data, we learn a regressor for on-the-fly detail synthesis during animation to enhance the perceptual realism of the avatars. Our system demonstrates that the use of appropriate reconstruction priors yields compelling face rigs even with a minimalistic acquisition system and limited user assistance. This facilitates a range of new applications in computer animation and consumer-level online communication based on personalized avatars. We present realtime application demos to validate our method.
