One of the most crucial aspects 3D facial models is reconstruction. However, it unclear if face shape distortion caused by identity or expression when morphable model (3DMM) fitted into largely expressive faces. In order to overcome problem, we introduce neural networks reconstruct stable and precise faces in time. The reconstruction network extracts 3DMM parameters from video sequences represe...

Ground settlement is often the most serious concern when tunneling under an old city with numerous historic monuments. A successful engineering design under these conditions would require getting the most out of the ground strength parameters and avoiding any weakening maneuver throughout the operation. Knowing that surface settlement is highly affected by tunneling parameters in EPB shield tun...

B-spline based deformable model is commonly used in recovering three-dimensional (3D) cardiac motion from tagged MRI due to its compact description, localized continuity and control flexibility. However, existing approaches usually ignore an important well-known fact that myocardial tissue is incompressible. In this paper, we propose to reconstruct 3D cardiac motion from tagged MRI using an inc...

Magnetic resonance elastography (MRE) is an important new method used to measure the elasticity or stiffness of tissues in vivo. While there are many possible applications of MRE, breast cancer detection and classification is currently the most common. Several groups have been developing methods based on MR and ultrasound (US). MR or US is used to estimate the displacements produced by either q...

This paper addresses the processing and reconstruction of the heart from echocardiographics images. This work is divided into two processing chains: reconstructionvisualization, each one of them is divided in several modules denominated as: 3D Acquisition, 3D Filtration, 3D Segmentation, 3D Reconstruction, 3D Modeling and 3D Visualization. The second processing chain uses a priori model of the ...

The purpose of this study was to investigate the relationship between three-dimensional (3D) deformation patterns in the canine left ventricle and localized graded reductions in perfusion. Magnetic resonance (MR) tissue tagging in a clinical scanner was used to determine systolic 3D deformation throughout the left ventricle with 32-msec time resolution. Six dogs were studied at normal and reduc...
