Arc2Avatar: Generating Expressive 3D Avatars from a Single Image via ID Guidance

Figure 1. Arc2Avatar creates detailed 3D head avatars from a single image with unprecedented realism and identity similarity through a carefully designed score distillation sampling approach on top of an adapted 2D face foundation model. Our method supports blendshapedriven expression generation by retaining dense correspondence between the 3D Gaussian Splats and an underlying facial mesh template.
