fault zones and fault-related fracture systems control the mechanical behaviors and fluid-flow properties of the earth’s crust. furthermore, nowadays, modeling is being increasingly used in order to understand the behavior of rock masses, and to determine their characteristics. in this work, fault zones and fracture patterns are reviewed, and also comprehensive studies are carried out on the fr...

lack of trust is one of the key bottle necks in e-commerce development. nowadays many advanced technologies are trying to address the trust issues in e-commerce. one among them suggests using suitable user interfaces. this paper investigates the functionality and capabilities of 3d graphical user interfaces in regard to trust building in the customers of next generation of b2c e-commerce websit...

A real-time system for tracking and modeling of faces using an analysis-by-synthesis approach is presented. A 3D face model is texture-mapped with a head-on view of the face. Feature points in the facetexture are then selected based on image Hessians. The selected points of the rendered image are tracked in the incoming video using normalized correlation. The result is fed into an extended Kalm...

Automated human face recognition is required in numerous applications. While considerable progress has been made in color/two dimensional (2D) face recognition, three dimensional (3D) face recognition technology is much less developed. 3D face recognition approaches based on the appearance of range images and geometric properties of the facial surface have been proposed. Methods that combine 2D...

The survival of an individual in a socially complex world depends greatly on the ability to interpret visual information about the age, sex, race, identity and emotional state of another person based on that person’s face. Despite a variety of different adverse conditions (varying facial expressions and facial poses, differences in illumination and appearance), humans can perform face identific...

We present a novel algorithm for the markerless tracking of deforming surfaces such as faces. We acquire a sequence of 3D scans along with color images at 40Hz. The data is then represented by implicit surface and color functions, using a novel partition-of-unity type method of efficiently combining local regressors using nearest neighbor searches. Both these functions act on the 4D space of 3D...

This paper presents automatic face authentication from facial surface analysis. This geometrical approach was motivated by diiculties encountered when considering frontal face recognition. Apart from being less sensitive to viewpoint and lighting conditions, the method exploits information which is complementary to grey level based approaches, enabling the fusion with those techniques. A 3D acq...

Three-dimensional face dense alignment and reconstruction in the wild is a challenging problem as partial facial information commonly missing occluded large pose images. Large head variations also increase solution space make modeling more difficult. Our key idea to model occlusion decompose this task into several relatively manageable subtasks. To end, we propose an end-to-end framework, terme...
