Face Recognition and Expression Recognition using Morphable Models
<P>IN THIS THESIS, WE PROPOSE A MORPHABLE MODEL CONSTRUCTION FRAMEWORK THAT MINIMIZES BOTH THE GLOBAL DISTANCE BETWEEN SURFACES (GLOBAL ENERGY) AS WELL AS THE DISTANCE BETWEEN CORRESPONDING FACE FEATURES ON DIFFERENT FACES (LOCAL ENERGY). LOCALIZED FACE FEATURE POINTS SUCH AS EYE CENTERS, NOSE-TIP, …

3D Morphable Models: Data Pre-Processing, Statistical Analysis and Fitting
… research aimed at using a 3D linear statistical model (known as a 3D morphable model) of an object class (which could be faces, bodies, cars, etc) for robust shape recovery. Our aim is to use this recovered information for the purposes of potentially useful applications like recognition and …

Towards trainable man-machine interfaces : combining top-down constraints with bottom-up learning in facial analysis
… facial analysis. We propose the use of a linear morphable model (LMM) for representing top-down structure and use it to model various facial variations such as mouth shapes and expression, the pose of faces and visual speech (visemes). We apply a supervised learning method based on support vector …

An accurate and efficient method for reconstruction of 3D faces from stereo images
… for reconstructing the 3D shape and texture model of human faces from two stereo images which are captured from calibrated cameras. Our approach works in a sparse to dense manner: we first build a coarse shape estimation based on 3D keypoints, and then use a linear morphable model to …

Trainable videorealistic speech animation
… work are * a variant of the multidimensional morphable model (MMM) [4] [26] [25] to synthesize new, previously unseen mouth configurations from a small set of mouth image prototypes, * a trajectory synthesis technique based on regularization, which is automatically trained from the recorded …

Gaze Estimation with Graphics
… vision strategy that couples a generative model of image formation (synthesis) with a perceptive model of scene comparison (analysis). The goal is to synthesize an image that best matches an observed image. In this dissertation I present three main contributions. First, I present a new …

Articulated Statistical Shape Modelling of the Shoulder Joint
… via the use of articulated statistical shape models (ASSMs). Articulated statistical shape models extend conventional statistical shape models by combining the shape variability of anatomical objects collected from different subjects (statistical shape models), with the physical variation of …

Reconstruction of three-dimensional facial geometric features related to fetal alcohol syndrome using adult surrogates
… from a single 2D image of the face using a 3D morphable model (3DMM) were explored in this research study. The research project was accomplished in several steps. 3D facial data were obtained from the publicly available BU-3DFE database, developed by the State University of New York. The 3D …

Three-Dimensional Body Volume Measurement From Two-Dimensional Images: Towards A Smartphone Application
… images, using a full body 3D Gaussian process morphable model (GPMM). Separate GPMMs were trained to learn the shape of female and male human bodies. Gaussian process regression of the three-dimensional (3D) GPMM models onto two-dimensional (2D) images is performed. Corresponding landmarks on …

3D face processing for animation and biometrics
… algorithms for facial feature detection, 3D model fitting and tracking from static and dynamic 2D and 3D visual signal input. We also demonstrate the applications of 3D face modeling in avatar animation, expression recognition and eye gaze estimation. The algorithms contribute to a complete …
