Retouch transfer for 3D printed face replica with automatic alignment
Seung‐Tak Noh, Takeo Igarashi · 2017
Recent developments in 3D scanning make it easy to obtain 3D geometry of a human and produce a 3D replica using a 3D printer. However, the setting for full body scanning enforces low-quality of the facial area due to the lack of image resolution. To solve this issue, artists retouch the raw scanned full body model with a 3D sculpting tool, but it takes a lot of time and effort. In this paper, we present a system to automate the retouching process by transferring a retouched result by an expert to an arbitrary target face model. Our method first identifies facial features, such as the eyes and nose of the 3D models by exploiting 2D face detection. For each facial part, the method establishes dense correspondences between the exemplar and the target using the detection result, and then transfers the geometry of the exemplar to the target by coating transfer. We show that our method improves not only the geometry of model but also the 3D printed replica.
