Overview of FaceCraft4D. Our approach begins with estimating the geometry of a single input image using a Geometry Prior. This geometry guides the synthesis of personalized multiview images, providing 360° views and varied expressions, with support from both 2D image and video priors. Since the synthesized data often exhibit inconsistency across views, we propose COIN optimization for robust 4D optimization. By fitting the model to the multiview data, we achieve our final 4D avatar.
