A major consideration in state-of-the-art face recognition systems is the amount of data that is required to represent a face. Even a small (64×64) photograph of a face has 2 dimensions in which a face may sit. When large (> 1MB) photographs of faces are used, this represents a very large (and practically intractable) space and ways of reducing dimensionality without losing discriminatory infor...

The idea of 3D stacking architecture was initially introduced to postpone the end of Moore’s law for CMOS technology. By stacking dies vertically on each other and connecting them with die-to-die vias, overall timing and energy efficiency improve due to better routing and shorter wires. It also introduces the notion of mixed process technology integration, connecting dies with different process...

This paper explores the use of multi-instance enrollment as a means to improve the performance of 3D face recognition. Experiments are performed using the ND-2006 3D face data set which contains 13,450 scans of 888 subjects. This is the largest 3D face data set currently available and contains a substantial amount of varied facial expression. Results indicate that the multi-instance enrollment ...

A three dimensional realistically shaped mathematical model, to investigate temperature distribution in a 3D IC has been developed taking into account heat carried by thermal vias and heat generation by the heat sources in the various device layers. Keeping in view the various heterogeneous variations of the thermo physical parameters and nature of the various layers, the 3D IC has been divided...

We propose a vector representation (called a 3D signature) for 3D face shape in biometrics applications. Elements of the vector correspond to fixed surface points in a face-centered coordinate system. Since the elements are registered to the face, comparisons of vectors to produce match scores can be performed without a probe to gallery alignment step such as an invocation of the iterated close...

In the last decades, a lot of 3D face recognition techniques have been proposed. They can be divided into three parts, holistic matching techniques, feature-based techniques and hybrid techniques. In this paper, a hybrid technique is used, where, a prototype of a new hybrid face recognition technique depends on 3D face scan images are designed, simulated and implemented. Some geometric rules ar...

Foreword The concept of obsolescence in the industrial sector has many facets that can be summarised in the general definition provided by the International Institute for Obsolescence Management (IIOM): obsolescence is the unavailability of parts, or services, that were previously available (IIOM 2015). The need to understand, plan and mitigate obsolescence (i.e. obsolescence management) is par...

background : improvement of facial beauty is a major reason why patients with dentofacial problems opt for orthognathic surgery. people are eventually judged by their facial appearance by themselves, their friends & family and even surgeons. with the recent developments in technology, we now have a 3d structure that can build and analyze 3d images before & after surgery and review the extent of...
