Animal Reconstruction with 3D Morphable Models
… thesis proposes a solution based on using 3D morphable models (3DMMs) as a useful intermediary 3D animal representation, enabling identification of adverse events and reducing the task-specific data requirements for downstream behaviour/welfare prediction tasks. A 3DMM is a specially designed …

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
… 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 synthesis. With a 3D …

Modelling non-linearity in 3D shapes: A comparative study of Gaussian process morphable models and variational autoencoders for 3D shape data
… the reliability of linear statistical shape models (SSM). This problem is regularly acknowledged, but disregarded, as it is assumed that linear models are able to adequately approximate such non-linearities. Model reliability is crucial for medical imaging and computer vision tasks; however, …

Comparing visual features for morphing based recognition
… correspondences between pairs of images. Various morphable models are created by small subsets of these correspondences using thin-plate spline. Given these morphs, a simple algorithm, least median of squares (LMEDS), is used to find the best morph. A scoring metric, using both LMEDS and distance …

Geometrically and Perceptually Accurate Facial Mesh Synthesis and Personalised Blendshapes Generation using Graph Neural Networks
… have led to the development of data driven models. These approaches are at the forefront of content creation technologies, offering artists and users the ability to rapidly generate and edit character assets. Despite major improvements in recent years, the geometric and perceptual quality of …
