Acquisition and modeling of material appearance

In computer graphics, the realistic rendering of synthetic scenes requires a precise description of surface geometry, lighting, and material appearance. While 3D geometry scanning and modeling have advanced significantly in recent years, measurement and modeling of accurate material appearance have remained critical challenges. Analytical models are the main tools to describe material appearanc...

3D digital stereophotogrammetry: a practical guide to facial image acquisition

The use of 3D surface imaging technology is becoming increasingly common in craniofacial clinics and research centers. Due to fast capture speeds and ease of use, 3D digital stereophotogrammetry is quickly becoming the preferred facial surface imaging modality. These systems can serve as an unparalleled tool for craniofacial surgeons, proving an objective digital archive of the patient's face w...

Using Dynamic 3D Facial Data to Create Appearance Models

We then perform a Principal Component Analysis on the training data matrix and obtain a set of Eigen vectors which represent the different Modes of Variations of the facial dynamics. We usually reorder the Eigen vectors by intensity. Considering that 98% of the variations are usually contained in the first 10 modes, we can reduce the high dimensionality of our model and improve at the same time...

Facial Ethnic Appearance Synthesis

In this work, we have explored several subspace reconstruction methods for facial ethnic appearance synthesis (FEAS). In our experiments, our proposed dual subspace modeling using the Fukunaga Koontz transform (FKT) yields much better facial ethnic synthesis results than the `1 minimization, the `2 minimization and the principal component analysis (PCA) reconstruction method. With that, we are ...

A comparative study of facial appearance modeling methods for active appearance models

Active appearance models (AAMs) have been widely used in many face modeling and facial feature extraction methods. One of the problems of AAMs is that it is difficult to model a sufficiently wide range of human facial appearances, the pattern of intensities across a face image patch. Previous researches have used principal component analysis (PCA) for facial appearance modeling, but there has b...
