The human face is a very important feature as it contains vital elements like the eyes, nose, lips, and eyelids. Numerous factors can damage soft tissue in the face causing functional and cosmetic defects. One of the common causes of disfiguring facial scars is burns. There are different methods of reconstruction each with their own merits and demerits. Herein, we describe a method for the faci...

Security and privacy issues remains a major hurdle in wide deployment of biometric based authentication system. For example, unauthorized access or regeneration of face templates has serious implications on the privacy of the concerned users. For robust and practical implementation of such system it is necessary to identify and explore the possible ways by which reconstruction of template is fe...

OBJECTIVES/HYPOTHESIS To describe a modified facial nerve reconstruction technique for complex defects of the facial fan after parotid surgery that avoids synkinesis between upper and lower face. STUDY DESIGN Retrospective case series. METHODS Patients who had undergone radical parotidectomy with a large defect of the facial fan, reconstruction of the upper face by facial nerve interpositio...

In this paper we propose a system for 3D face reconstruction from 2D stereo images. Two different stereo matching algorithms are presented; the first is a local method that finds the correspondences of 15 most characteristic facial fiducial points, whose 3D reconstruction allows us to deform a parameterized sparse model. The second method employs a snake grid algorithm which minimizes a multi-r...

3D face reconstruction is essential for a number of applications. Most approaches are aimed at producing accurate models and make use of high levels of control to achieve this, such as through restricted motion, structured light, or specialist equipment. However, there is also a considerable market for reconstructions in uncontrolled environments but where a lower level of accuracy is acceptabl...

BACKGROUND Atrial en-face reconstructions are commonly used to assess mitral valve morphology in three dimensional (3D) echocardiography but may miss important abnormalities. OBJECTIVE To present a systematic method for the analysis of the regurgitant mitral valve using a combination of en-face and longitudinal views for better anatomical evaluation. METHODS Detailed 3D assessment was done ...

In comparison with 2D face images, 3D face models have the advantage of being illumination and pose invariant, which provides improved capability of handling changing environments in practical surveillance. Feature detection, as the initial process of reconstructing 3D face models from 2D uncalibrated image sequences, plays an important role and directly affects the accuracy and robustness of t...

Facial injuries are often accompanied by soft tissue injuries. The complexity of these injuries is represented by the potential for loss of relationships between the functional and the aesthetic subunits of the head. Most reviews of craniofacial trauma have concentrated on fractures. With this article, we want to emphasize the importance of early aesthetic reconstruction of the face in polytrau...

Today, three dimensional (3D) reconstruction of human face is gaining more importance, with many applications. Among the various methods, this paper uses shadow moiré method which has superiorities over other methods. In shadow moiré method an iterative three-step phase shifting method is proposed which increases the measurement accuracy by eliminating nonuniform phase shift error. The method i...
