In this paper we propose to use our body as a puppetry controller, giving life to a virtual silhouette through acting. A framework was deployed based on Microsoft Kinect using OpenNI and Unity to animate in real-time a silhouette. This was used to perform a set of experiments related to the user's interaction with human and non-human like puppets. We(More)
Character animation has traditionally relied on complex and time-consuming key frame animation or expensive motion capture techniques. These methods are out of reach for low budget animation productions. We present a low-cost performance-driven technique that allows real-time interactive control of puppets for performance or film animation. In this paper we(More)
Many authors have studied the correlation of cranial base flexure and the degree of mandibular prognathism and classification of malocclusion. This indicates that the cranial base flexure may or may not have an effect on the degree of mandibular prognathism and classification of malocclusion. This study evaluates the correlation of the pretreatment cranial(More)
BACKGROUND Fast and accurate chest pain risk stratification in the emergency department (ED) is critical. The HEART score predicts the short-term incidence of major adverse cardiac events (MACE) in this population, dividing it in three risk categories. We aimed to describe the population with chest pain, to characterize the subgroup of patients with acute(More)
Virtual Marionette is a research on digital puppetry, an interdisciplinary approach that brings the art of puppetry into the world of digital animation. Inspired in the traditional marionette technology our intention is to study novel interfaces as an interaction platform for creating artistic contents based on computer animated puppets. The overall goal of(More)
BACKGROUND Multi-vessel disease is frequent in patients presenting with myocardial infarction and have an important prognostic impact. The decision to proceed to revascularization in non-culprit vessels can be postponed until ischemia is proven in non-invasive stress tests. On the other hand, there is an increasing evidence to support the role of fractional(More)
OBJECTIVE To evaluate the position of the mandibular first permanent molar in the mandible relative to several factors. MATERIALS AND METHODS A total of 185 untreated Class I and Class II patients were randomly selected from a sample of 350 patients from a single office. The palatal and mandibular planes were related to Frankfort horizontal to create the(More)
Cardiotocographic signals, used as a perinatal diagnostic tool, comprise fetal heart beat signals (FHR), uterine contractions (UC) and fetal movements (FM). Visual inspection of these three signals is limited, subjective, time consuming and with low reproducibility. The present paper illustrates an application of signal processing techniques to the(More)
During routine ultrasound examination of 178 normal pregnant women at 17-24 weeks, several biometric measurements were performed including transverse cerebellar diameter, cavum septum pellucidum, anterior and posterior horns of cerebral ventricles and nuchal soft tissue. The transverse cerebellar diameter is easy to obtain at this gestational age even in(More)
