3D techniques are increasingly used in aerospace industry to improve quality and performance of aircrafts. This paper presents a 3D imaging technique for studying the aerodynamic shape and flight performance of micro air vehicles. 3D stereoscopic vision, based upon stroboscopic imaging, was utilized to obtain the 3D information of the aircraft’s flexible aerodynamic surface. The aircraft models...

We describe ArtiSynth, a 3D biomechanical simulation platform directed toward modeling the vocal tract and upper airway. It provides an open-source environment in which researchers can create and interconnect various kinds of dynamic and parametric models to form a complete integrated biomechanical system which is capable of articulatory speech synthesis. An interactive graphical Timeline runs ...

This paper explores enhancing mobile immersive augmented reality manipulations by providing a sense of computer-captured touch through the use of a passive deformable haptic glove that responds to objects in the physical environment. The glove extends our existing pinch glove design with a Digital Foam sensor that is placed under the palm of the hand. The novel glove input device supports a ran...

We present a novel Learning from Demonstration (LfD) method, Deformable Manipulation Demonstrations (DMfD), to solve deformable manipulation tasks using states or images as inputs, given expert demonstrations. Our method uses demonstrations in three different ways, and balances the trade-off between exploring environment online guidance experts explore high dimensional spaces effectively. test ...

This paper gives architecture and implementation details of a hand tracking and gesture recognition system which has been developed at Olivetti Research Limited as an application for the Medusa distributed multimedia environment. The system uses live 15-bit colour video from a networked camera, runs in real time (25 frames/sec on a DEC Alpha), and copes well with background clutter. Tracking is...

deflection analysis of a simply supported microbeam subjected to a concentrated load at the middle is investigated on the basis of a shear deformable beam theory and non-classical theory. effects of shear deformation and small size are taken into consideration by hyperbolic shear deformable beam theory and modified strain gradient theory, respectively. the governing differential equations and c...

We propose an efficient image-matching method for deformable-object image matching using discrimination of deformable objects and geometric similarity clustering between feature-matching pairs. A deformable transformation maintains a particular form in the whole image, despite local and irregular deformations. Therefore, the matching information is statistically analyzed to calculate the possib...

We present a simple method for performing real-time collision detection in a virtual surgery environment. The method relies on the graphics hardware for testing the interpenetration between a virtual deformable organ and a rigid tool controlled by the user. The method enables to take into account the motion of the tool between two consecutive time steps. For our specific application, the new me...

Deformable image registration is a powerful tool for mapping information, such as radiation therapy dose calculations, from one computed tomography image to another. However, deformable image registration is susceptible to mapping errors. Recently, an automated deformable image registration evaluation of confidence tool was proposed to predict voxel-specific deformable image registration dose m...
