Global Alignment for Dynamic 3D Morphable Model Construction

University of Bath

Motivation

•3D Face Models

•3D Morphable Model [1]

•Dynamic 3D FACS Dataset [2]

•Corresponded Model for Facial Analysis

•Speech analysis in 3D

•Facial expression recognition

Rigid Alignment and UV Projection

•CPD (Coherent Point Drift) [3] vs ICP

•UV Projection use Maya

Local Non-Rigid Alignment

Local Non-Rigid Alignment

Global Non-Rigid Alignment

Evaluation: Optical Flow VS TPS+OF

Comparison between OF and TPS+OF

Statistical Model

•PCA Model

•Low-Dim Representation
