DeepFaceEditing: Deep Face Generation and Editing with Disentangled Geometry and Appearance Control

Accepted by Siggraph 2021

Figure:Our DeepFaceEditing method allows users to intuitively edit a face image to manipulate its geometry and appearance with detailed control. Given a portrait image (a), our method disentangles its geometry and appearance, and the resulting representations can faithfully reconstruct the input image (d). We show a range of flexible face editing tasks that can be achieved with our unified framework: (b) changing the appearance according to the given reference images while retaining the geometry, (c) replacing the geometry of the face with a sketch while keeping the appearance, (e) editing the geometry using sketches, and (f) editing both the geometry and appearance. The inputs used to control the appearance and geometry are shown as small images with green and orange borders, respectively.

Recent facial image synthesis methods have been mainly based on conditional generative models. Sketch-based conditions can effectively describe the geometry of faces, including the contours of facial components, hair structures, as well as salient edges (e.g., wrinkles) on face surfaces but lack effective control of appearance, which is influenced by color, material, lighting condition, etc. To have more control of generated results, one possible approach is to apply existing disentangling works to disentangle face images into geometry and appearance representations. However, existing disentangling methods are not optimized for human face editing, and cannot achieve fine control of facial details such as wrinkles. To address this issue, we propose DeepFaceEditing, a structured disentanglement framework specifically designed for face images to support face generation and editing with disentangled control of geometry and appearance. We adopt a local-to-global approach to incorporate the face domain knowledge: local component images are decomposed into geometry and appearance representations, which are fused consistently using a global fusion module to improve generation quality. We exploit sketches to assist in extracting a better geometry representation, which also supports intuitive geometry editing via sketching. The resulting method can either extract the geometry and appearance representations from face images, or directly extract the geometry representation from face sketches. Such representations allow users to easily edit and synthesize face images, with decoupled control of their geometry and appearance. Both qualitative and quantitative evaluations show the superior detail and appearance control abilities of our method compared to state-of-the-art methods.
