Reconstruction and manipulation of portraits
Guoxian Song · 2022
The large growth in consumer digital cameras and smart phones has led to prevalent use of digital photography. One typical category is portraiture, where a photograph is taken of a person's face or upper body. Analysis of portraits for 3D reconstruction and further manipulation has received a lot of attention, as it is highly relevant to Virtual Reality (VR) and Augmented Reality (AR), as well as other forms of entertainment. This thesis presents my research contributions to image-based facial analysis, involving 3D facial geometry estimation and facial reflectance inference as well as advanced manipulation techniques for portrait relighting, shadow generation and portrait stylization.
