Titel
Fast, robust and automatic 3D face model reconstruction from videos
Abstract
This paper presents a fully automatic system that recovers 3D face models from sequences of facial images. Unlike most 3D Morphable Model (3DMM) fitting algorithms that simultaneously reconstruct the shape and texture from a single input image, our approach builds on a more efficient least squares method to directly estimate the 3D shape from sparse 2D landmarks, which are localized by face alignment algorithms. The inconsistency between self-occluded 2D and 3D feature positions caused by head pose is ad-dressed. A novel framework to enhance robustness across multiple frames selected based on their 2D landmarks combined with individual self-occlusion handling is proposed. Evaluation on ground truth 3D scans shows superior shape and pose estimation over previous work. The whole system is also evaluated on an 'in the wild' video dataset [12] and delivers personalized and realistic 3D face shape and texture models under less constrained conditions, which only takes seconds to process each video clip.
