3D Face Recognition is an active area of research for past several years. For a 3D face recognition system one would like to have an accurate as well as low cost setup for constructing 3D face model. In this paper, we use Profilometry approach to obtain a 3D face model. This method gives a low cost solution to the problem of acquiring 3D data and the 3D face models generated by this method are ...

Face recognition in uncontrolled environments is hindered by variations in illumination, pose, expression and occlusions of faces. Many practical face-recognition systems are affected by these variations. One way to increase the robustness to illumination and pose variations is to use 3D facial images. In this paper 3D face-recognition systems are presented. Their structure and operation are de...

3D facial data has a great potential in overcoming the problems of illumination and pose variation in face recognition. In this paper, we investigate face recognition from range data by facial profiles and surface. An efficient symmetry plane detection method for facial range data is presented to help extract facial profile. A global profile matching method is then exploited to align and compar...

Automatic face recognition is becoming increasingly important due to the security applications derived from it. Although the face recognition problem has focused on 2D images, recently, due to the proliferation of 3D scanning hardware, 3D face recognition has become a feasible application. This 3D approach do not use the colour of the faces, so, when it is compared to the more traditional 2D ap...

This article presents key research needs in three-dimensional integrated circuit (3D IC) architectural floorplanning. Architectural floorplaning is done at a very early stage of 3D IC design process, where the goal is to quickly evaluate architectural designs described in register-transfer level (RTL) in terms of power, performance, and reliability. This evaluation is then fed back to architect...

With the development of computer vision and computer graphics, face recognition technology has gradually developed from 2D to 3D. Using in-depth information of faces, 3D face recognition solves and overcomes the environment and changes in the expression that 2D face recognition encounters. In this paper, the principles of laser triangulation measurement applied in 3D detection and modeling of f...

3D printing has been hailed as a game changer in the manufacturing sector, with major imprints across multiple domains. Players from several industries are investing heavily in 3D printing, with the possibility of extending its applicability to daily use products coming to the fore. With speculation and limited information blurring the line between reality and fiction, it is critical to analyze...

3D printing services are appearing, allowing consumers or businesses to order custom parts for delivery within a quoted lead-time, regardless of design specification. The manufacturer’s problem is to ensure that customers receive their goods on time, while capacity costs (including overtime costs) are kept low. We introduce a performance measure called the service rate, analogous to the fill ra...

Ability to stack separate chips in a single package enables three-dimensional integrated circuits (3D ICs). Heterogeneous 3D ICs provide even better opportunities to reduce the power and increase the performance per unit area. An important issue in designing a heterogeneous 3D IC is reliability. To achieve this, one needs to select the data mapping and processor layout carefully. In this paper,...

Additive manufacturing has spread widely over the past decade, especially with the availability of home 3D printers. In the future, many items may be manufactured at home, which raises two ethical issues. First, there are questions of safety. Our current safety regulations depend on centralized manufacturing assumptions; they will be difficult to enforce on this new model of manufacturing. Usin...
