Even though 3D toolkits and technologies are rapidly evolving, the development of three-dimensional applications is still very complicated and hard work due to format dependencies, missing standards and lack of software engineering support. Component-based development seems to be promising, where interactive 3D software will be composed of flexible and reusable 3D interface components. We prese...

This paper presents the work leading to the launch of a laboratory for digital 3D imaging dedicated to the establishment of a permanent digital heritage preservation centre in Florence. By applying the latest non-contact 3D technologies and methodologies, this center intends to create a bridge between expectations of art historians and curators, and, the people promoting these new 3D technologi...

Many assistive technologies, although designed to enhance quality of life, become a headache for users. Price, fit, and comfort level are chief assailants in the total acceptance of certain assistive technologies – for many AT users, “one size fits all” doesn’t. By utilizing software developed to integrate Microsoft Kinect, openSCAD, and MakerBot 3D printers, we strove to develop a system inten...

We study a firm’s manufacturing strategy under two types of flexible production technologies: the traditional flexible technology and 3D printing. Under the traditional flexible technology, capacity becomes more expensive as it handles more product variants; under 3D printing, however, capacity cost is independent of the number of product variants processed. The firm adopts a dedicated technolo...

Nanobiomaterials play an important role in nanobiotechnology and have made a great contribution to biomedical research and healthcare. Recent progress in nanobiomaterials has increased demand for multidisciplinary approaches from physical, biological and engineering sciences. Solid freeform fabrication (SFF) technologies are based on layer-by-layer deposition of materials which bring about new ...

In this paper, a noble nonintrusive three-dimensional (3D) face modeling system for random-profile-based 3D face recognition is presented. Although recent two-dimensional (2D) face recognition systems can achieve a reliable recognition rate under certain conditions, their performance is limited by internal and external changes, such as illumination and pose variation. To address these issues, 3...

Face recognition in presence of illumination changes, variant pose and different facial expressions is a challenging problem. In this paper, a method for 3D face reconstruction using photometric stereo and without knowing the illumination directions and facial expression is proposed in order to achieve improvement in face recognition. A dimensionality reduction method was introduced to represen...

Figure 1: COG descriptor encodes orientation-invariant gradient feature for objects with different views. I develop new representations and algorithms for three-dimensional (3D) scene understanding from cluttered indoor RGB-D images and outdoor video sequences. I introduce novel representations for 3D object detection systems that localize objects with cuboids and describe room layouts by Manha...
