3D Face Reconstruction from Stereo: A Model Based Approach

Abstract

Since the human faces are lowly textured, the conventional stereo methods based on intensity correlation can not give satisfying 3D face reconstruction results. In this paper, a model based stereo matching method is proposed. A reference 3D face is used as an intermedium for correspondence calculation. The virtual face images with known correspondences are first synthesized from the reference face. Then the known correspondences are extended to the incoming stereo face images, using face alignment and warping. The complete 3D face can thus be reconstructed from stereo images reliably.
