Analysis of Coded Apertures for Defocus Deblurring of HDR Images
(The Eurographics Association, 2012)In recent years, research on computational photography has reached important advances in the field of coded apertures for defocus deblurring. These advances are known to perform well for low dynamic range images (LDR), but ... -
Ventricular Puncture Trainer
(The Eurographics Association, 2012)The learning process in neurosurgery is a large and difficult task based on experimentation, being ventriculostomy not an exception. We have developed a virtual reality system to help training novel surgeons on this kind ... -
3D Interaction with Smartphone-like Devices
(The Eurographics Association, 2012)3D applications require a series of 3D operations that are difficult to perform with the traditional interaction devices such as mouse and keyboard. In this paper we present a new 3D interaction system using smartphone-like ... -
Visual Language Generalization for Procedural Modeling of Buildings
(The Eurographics Association, 2012)Procedural modeling has become the accepted standard for the creation of detailed large scenes, in particular urban landscapes. With the introduction of visual languages there has been a huge leap forward in terms of ... -
Interactive Generation of (Paleontological) Scientific Illustrations from 3D-models
(The Eurographics Association, 2012)Scientific illustrations play an important role in the paleontological domain and are complex illustrations that are manually drawn. The artist creates illustrations that feature common expressive painting techniques: ... -
Non-rigid 3D Faces Registration using Geodesic Distance Maps
(The Eurographics Association, 2012)3D facial mesh registration is a key step in 3D facial analisys. This process calculates a mapping between faces in order to put in correspondence each point of both faces. In this poster we introduce a new approach for ... -
A New Approach to Explore Integral Field Spectroscopy Data
(The Eurographics Association, 2012)Integral field spectroscopy (IFS) is a technique that is widely used in astronomy. It gives simultaneously the spectra of each spatial sampling element of a given field, generating a large amount of information that is ... -
Tracking for Virtual Environment using Kinect
(The Eurographics Association, 2012)Los sistemas de tracking magnético suelen tener alcance limitado y presenta problemas de interferencias. En este trabajo proponemos utilizar los sensores de kinect para realizar el tracking en sistemas HMD. -
Generating Coherent Ray Directions in Path Tracing
(The Eurographics Association, 2012)The quality of the images produced by a global illumination rendering engine is highly connected to the number of paths that are randomly generated from the camera to the light sources. Graphics Processing Units (GPUs) ... -
A Procedural Modeling System for the Creation of Huge Models
(The Eurographics Association, 2012)This paper presents a new general purpose procedural geometrical modeling system. It is focused on providing flexibility, modularity and scalability. Furthermore, it is taylored to manage huge geometric models, with millions ... -
Evaluating Three Versions of an Augmented Reality Mobile Game about Recycling
(The Eurographics Association, 2012)We present three versions of an Augmented Reality (AR) game (basic, collaborative and competitive) for changing people attitudes with regard to climate change. We present a study in which twenty-eight primary school students ... -
An Application to Interact with 3D Models Reconstructed from Medical Images
(The Eurographics Association, 2012)Although the reconstruction of 3D models from medical images is not an easy task, there are many algorithms to perform it. However, the reconstructed models are usually large, have a lot of outliers and have not a correct ... -
Teaching Tool for Self-learning and Self-evaluation of Human Anatomy Using 3D Models of Human Bones
(The Eurographics Association, 2012)In this research, it's going to introduce the process we have applied by development an application intended to students of Physioteraphy Studies, The proccess is divided by three sub-process: scanning bones, processing ... -
A GPU Based Method for the Automatic Generation of Near-Optimal Navigation Meshes
(The Eurographics Association, 2012)In this paper we present a novel, robust and efficient GPU based technique to automatically generate a Navigation Mesh for complex 3D scenes. Our method consists of two steps: firstly, starting with a 3D scene representing ... -
Kinamo: Gait Analysis System
(The Eurographics Association, 2012)The gait analysis is a fundamental technique for functional assessment of patients with gait problems. This analysis is generally available to few patients because the systems needed to carry it out have a high cost. In ... -
A Survey on Development Tools for Mobile Augmented Reality
(The Eurographics Association, 2012)Augmented Reality (AR) applications have become more popular beyond the research laboratory due to recent technological breakthroughs in computer hardware and mobile devices. Users are starting to interact with virtual ... -
Modular Design of Graph Theory Based Software for Scientific Applications and Education
(The Eurographics Association, 2012)This work describes a new software design approach in graph theory applications. Sometimes, while using or teaching applications related to this subject, one of the main drawbacks is to define the application-specific graph ... -
Bringing Direct Local Control to Interactive Visual Editing of Procedural Buildings
(The Eurographics Association, 2012)This paper presents a new system to add direct and persistent local control to the visual editing of rules for procedural buildings, avoiding a combinatorial explosion of grammar rules. In this paper we follow the ideas ... -
