Improving 2D-3D Registration by Mutual Information using Gradient Maps
(The Eurographics Association, 2010)In this paper we propose an extension for the algorithms of image-to-geometry registration by Mutual Information( MI) to improve the performance and the quality of the alignment. Proposed for the registration of multi modal ... -
Improving and Optimising Visualisations of Full-waveform LiDAR Data
(The Eurographics Association, 2016)Visualisations of Remotely Sensed data has a significant role in forestry. Foresters have a great knowledge about forests (for example they can identify tree diseases) and they can derive a wealth of information directly ... -
Improving Depth Estimation Using Superpixels
(The Eurographics Association, 2014)This work is focused on assigning a depth label to each pixel in the image. We consider off-the-shelf algorithms that provide depth information from multiple views or depth information directly obtained from RGB-d sensors. ... -
Improving Ray Tracing Performance with Variable Rate Shading
(The Eurographics Association, 2021)Hardware-accelerated ray tracing has enabled ray traced reflections for real-time applications such as games. However, the number of traced rays during each frame must be kept low to achieve expected frame rates. Therefore, ... -
Improving text entry performance on tablet devices
(The Eurographics Association, 2020)In order to improve the text entry speed and error rate on tablet devices, we developed and tested 5 virtual keyboard variants. Some variants try to avoid errors by highlighting the next four most probable keys, either by ... -
IN2TUNNEL - Terapia de Exposição para Fobia de Atravessar Túneis
(The Eurographics Association, 2020)O uso da Realidade Virtual na Terapia de Exposição (RVTE) permite que um paciente seja exposto à situação temida, sem recorrer a uma exposição real o que é particularmente vantajoso quando a reprodução da situação real é ... -
Inclusão de superficies especulares em radiosidade
(The Eurographics Association, 2023)Neste trabalho apresenta-se um método de inclusão de superfícies especulares puras (espelhos) em radiosidade. Trata-se de um método a aplicar no primeiro dos dois passos tipicamente utilizados nestes casos, correspondendo ... -
Incremental Reconstruction Approach for Telepresence or AR Applications
(The Eurographics Association, 2020)This paper proposes an on-line incremental 3D reconstruction framework aimed at fulfilling the needs of telepresence or human machine interaction applications. The research presents a teleconference system that improves ... -
Indicators Basis for Functional Shape Analysis
(The Eurographics Association, 2018)Step functions are widely used in several applications from geometry processing and shape analysis. Shape segmentation, partial matching and self similarity detection just to name a few. The standard signal processing tools ... -
Indirect Illuminance Computation on GPU for Lighting CAD using CIE Basic Method
(The Eurographics Association, 2008)In this work, we focus our attention to near real time illuminance for Lighting CAD. The implemented model is the Basic Method CIE which is a simplified method used in interior lighting design; a pre-computational phase ... -
Individualizing the New Interfaces: Extraction of User's Emotions from Facial Data
(The Eurographics Association, 2006)When developing new multimodal user interfaces emotional user information may be of great interest. In this paper we present a simple and computationally feasible method to perform automatic emotional classification of ... -
Indoor Image Geocoding using Synthetic Views
(The Eurographics Association, 2020)The Global Positioning System is well known for not reaching indoor environments. Several Indoor Positioning System's have been proposed, but most of these solutions either have high accuracy errors or use expensive material ... -
Industrial Facility Modeling Using Procedural Methods
(The Eurographics Association, 2015)We present an end-to-end system for procedurally modeling an industrial facility. The system is a collection of utilities that work together to assemble, lay out, and model a typical industrial facility (e.g. a wastewater ... -
Inexpensive 3D Stereo for Two Users Using a Single Display
(The Eurographics Association, 2021)Multiuser computer systems allow several users to collaborate on the same task. Medium sized displays, like workbenches or tabletops provide a shared view of the task and a set of input devices to interface with the system. ... -
Influencing User Attention Using Real-Time Stylised Rendering
(The Eurographics Association, 2009)In this paper, we present a series of experiments that were conducted to further understand how using adaptive levels of artistic abstraction within an interactive 3D scene can influence user gaze behaviour. We found that ... -
Informação Logica na Modelação Geometrica
(The Eurographics Association, 2023)Durante a construçao de um modelo geométrico (fase de síntese do projecto), o projectista manipula diferentes tipos de informaçao, nomeadamente a que se prende com a definiçao geométrica e topológica do modelo e a que diz ... -
Information Visualization Attributes and Operators for a Web Log Based Management System
