   Nonlinear 3D Face Morphable Model

   Luan Tran, Xiaoming Liu

   As a classic statistical model of 3D facial shape and texture, 3D Morphable Model (3DMM) is widely used in facial analysis, including model fitting, image synthesis, etc. Conventional 3DMM is learned from a collection of wellcontrolled 2D face images with associated 3D face scans, and represented by two sets of ...

   Pose-Invariant Face Alignment (PIFA)

   Amin Jourabloo, Yaojie Liu, Xiaoming Liu

   Face alignment is a process of applying a supervised learned model to a face image and estimating the locations of a set of facial landmarks, such as eye corners, mouth corners, etc. Face alignment is a key module in the pipeline of most facial analysis algorithms, normally after face detection ...
