Hybrid ROI-based visualization of medical models
(2015)
Conference lecture
Open AccessThere is an increasing interest on tele-medicine and tele-diagnostic solutions based on the remote inspection of volume data coming from multimodal imaging. Client-server architectures meet these functionalities. The use ... -
Impact of filter feature selection on classification: an empirical study
(CEUR-WS.org, 2022)
Conference lecture
Open AccessThe high-dimensionality of Big Data poses challenges in data understanding and visualization. Furthermore, it leads to lengthy model building times in data analysis and poor generalization for machine learning models. ... -
Improving patient-reported outcome measures through visual analytics
(Universitat Politècnica de Catalunya, 2021-07-08)
Bachelor thesis
Open AccessIn this thesis the important role of visual analytics will be presented as it offers a better understanding of Patient-Reported Outcome Measures (PROMS). PROMS differ from the well-known medical measures, which are ... -
Improving perception accuracy in bar charts with internal contrast and framing enhancements
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Open AccessBar charts are among the most commonly used visualization graphs. Their main goal is to communicate quantities that can be visually compared. Since they are easy to produce and interpret, they are found in any situation ... -
Instant visualization of secondary structures of molecular models
