Proposed a representation scheme for 3D face -- Surface UnfoldingFor its irregular sampling in 3D space, 3D face surface cannot be processed by many orthogonal and subspace analysis toolkits directly, i.e. DFT, DCT, PCA, LCA. Surface Unfolding projects the 3D face to a 2D plane while retaining its intrinsic geometry properties of angle and area which issues a surface representation — Unfolded Image.

提出了一个三维人脸的平面表征方法——曲面开折模型不同于传统的数字生物特征，3D人脸数据是非规则采样的，传统的信号处理工具难以对3D数据进行直接处理。
