A novel algorithm is presented for the 3D reconstruction of human action in long (> 30 second) monocular image sequences.A sequence is represented by a small set of automatically found representative keyframes. The skeletal joint positions are manually located in each keyframe and mapped to all other frames in the sequence. For each keyframe a 3D key pose is created, and interpolation between t...

In this paper, we present a computer-assisted method for facial reconstruction. This method provides an estimation of the facial shape associated with unidentified skeletal remains. Current computer-assisted methods using a statistical framework rely on a common set of extracted points located on the bone and soft-tissue surfaces. Most of the facial reconstruction methods then consist of predic...

Plastic surgeons performing prosthetic breast reconstruction face a demanding task in manipulating and reconstructing the altered soft tissue envelope in patients with connective tissue disease (CTD). Despite the difficulties inherent to this unique patient population, there are no reports in the literature describing breast reconstruction or tissue expansion in patients with CTD. We therefore ...

metopism had been observed as a genetic trait. recent studies have brought to light that it can get as an indicator of cranial pathology. an example of this pathology has been studied by this author on an iranian skeletal sample. the purpose of this paper is to provide basic information on the subject and thereby to create awareness among iranian anthropologists and archaeologists of this new l...

intramuscular cavernous hemangiomas represent less than 1% of all hemangiomas. typical presentation is a soft-tissue mass and/or pain without cutaneous changes. whereas calcification of hemangiomas is common; ossification of these lesions is very rare. we describe a case of ossified intramuscular hemangioma of quadriceps presented with painless knee extension contracture and thigh mass.

magnetic resonance imaging (mri) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. the advantages and disadvantages of mri is not fully understood. in the computerized tumor (ct) scan, as an invasive method, the x-rays of the body is used for tomography; which different x-ray attenuation coefficient in tissues as well as...

Introduction: Quantitative evaluation is recommended to improve diagnostic ability and serial assessment of dopamine transporter (DAT) density scans. We decided to compare the ordered subsets expectation-maximization (OSEM) with filtered back-projection (FBP), and to investigate the impact of different iteration and cut-off frequencies on SBR values. Methods</stro...

Advanced model-based iterative reconstruction algorithms in quantitative computed tomography (CT) perform automatic segmentation of tissues to estimate material properties of the imaged object. Compared with conventional methods, these algorithms may improve quality of reconstructed images and accuracy of radiation treatment planning. Automatic segmentation of tissues is, however, a difficult t...

BACKGROUND The success of posterior cruciate ligament reconstruction has varied. The objective of this study was to determine quantitatively and qualitatively the topography and osseous landmarks of the femoral footprints of the anterolateral and posteromedial bundles of the posterior cruciate ligament in order to enhance repair. METHODS Twenty unpaired knees from twenty human cadavers were e...
