Although most structures are designed to function under small deformation, their large deformation behavior can be used to estimate reliability and safety for survivorship from an accident or a natural disaster. Structures such as buildings, bridges, ships, vehicles and machinery are designed with a safety factor to protect certain assets from the unexpected and unknot elements. The large defor...

We present a new approach for the non-rigid registration of contrastenhanced breast MRI using normalised mutual information. A hierarchical transformation model of the motion of the breast has been developed: The global motion of the breast is modelled using affine transformation models while the local motion of the breast is modelled using spline-based free-form deformation (FFD) models. The a...

The goal of this study is to develop a customised computer model that can accurately represent the motion of vocal articulators during vowels and consonants. Models of the articulators were constructed as Finite Element (FE) meshes based on digitised high-resolution MRI (Magnetic Resonance Imaging) scans obtained during quiet breathing. Articulatory kinematics during speaking were obtained by E...

In this paper, we propose a general framework for performance improvement of the current state-of-the-art registration algorithms in terms of both accuracy and computation time. The key concept involves rapid prediction of a deformation field for registration initialization, which is achieved by a statistical correlation model learned between image appearances and deformation fields. This allow...

a r t i c l e i n f o Satellite Radar Interferometry (InSAR) is suited to monitoring ground deformation on the scale of volcanic arcs, providing insight into the eruptive cycle over both long and short time periods. However, these measurements are often contaminated with atmospheric artefacts caused by changes in the refractivity of the atmosphere. Here, we test the use of two large-scale atmos...

This paper investigate the impact of packet size on the performance of 802.15.4 for Wireless Sensor Network based on various packet size scenario like packet size 300, 600 and 900.The comparative results have been reported for the performance metrics like Battery energy consumed, Traffic sink end to end delay and Traffic received. Packet size optimization is an important issue in energy constra...

Stevens Institute of Technology Hoboken, NJ, USA {hwang,[email protected]} Abstract. We study the privacy threat by publishing data that contains full functional dependencies (FFDs). We show that the cross-attribute correlations by FFDs can bring potential vulnerability to privacy. Unfortunately, none of the existing anonymization principles can effectively prevent against the FFD-based priv...

exp(2 i( p 1 i ) are the eigenvalues of the Milnor monodromy and their integral part is determined by the Hodge ltration of the mixed Hodge structure. This notion was rst introduced by Steenbrink [11]. By [14] the exponents are constant under -constant deformation of f . In particular, they depend only on f 1 (0). They express the vanishing order (up to the shift by one) of the period integrals...

In computer vision and image analysis, image registration between 2D projections and a 3D image while obtaining high accuracy and real-time computation is challenging. In this paper, we propose a novel method that can speedily detect the object’s 3D rigid motion or deformation from a small set of its 2D projection images. The method consists of two stages: registration and pre-registration lear...
