Effective visualization of sparse image-to-image correspondences
(European Association for Computer Graphics (Eurographics), 2020)
Conference report
Open AccessFinding robust correspondences between images is a crucial step in photogrammetry applications. The traditional approach to visualize sparse matches between two images is to place them side-by-side and draw link segments ... -
A Tool for N-way analysis of programming exercises
(European Association for Computer Graphics (Eurographics), 2020)
Conference report
Open AccessProgramming exercises are a corner stone in Computer Science courses. If used properly, these exercises provide valuable feedback both to students and instructors. Unfortunately, the assessment of student submissions through ... -
A semantic model to fight social exclusion
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessThis work presents a semantic model meant to help with the identification and prediction of individuals at risk of social exclusion. The model is based on the self-sufficiency matrix, a tool that evaluates a person's ... -
Co-occurrence patterns in diagnostic data
(Wiley (John Wiley & Sons), 2020-04-12)
Article
Open AccessWe demonstrate how graph decomposition techniques can be employed for the visualization of hierarchical co-occurrence patterns between medical data items. Our research is based on Gaifman graphs (a mathematical concept ... -
Multi-view image fusion
(2019)
Conference report
Open AccessWe present an end-to-end learned system for fusing multiple misaligned photographs of the same scene into a chosen target view. We demonstrate three use cases: 1) color transfer for inferring color for a monochrome view, ... -
A software service supporting software quality forecasting
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessSoftware repositories such as source control, defect tracking systems and project management tools, are used to support the progress of software projects. The exploitation of such data with techniques like forecasting is ... -
From process models to chatbots
(Springer, 2019)
Conference report
Open AccessThe effect of digital transformation in organizations needs to go beyond automation, so that human capabilities are also augmented. A possibility in this direction is to make formal representations of processes more ... -
Formal reasoning on natural language descriptions of processes
(Springer, 2019)
Conference report
Open AccessThe existence of unstructured information that describes processes represents a challenge in organizations, mainly because this data cannot be directly referred into process-aware ecosystems due to ambiguities. Still, this ... -
View-dependent hierarchical rendering of massive point clouds through textured splats
(European Association for Computer Graphics (Eurographics), 2019)
Conference report
Open AccessNowadays, there are multiple available range scanning technologies which can capture extremely detailed models of realworld surfaces. The result of such process is usually a set of point clouds which can contain billions ... -
Distance-uniform graphs with large diameter
(2019-06-01)
Article
Open AccessAn ϵ-distance-uniform graph is one with a critical distance d such that from every vertex, all but at most an ϵ-fraction of the remaining vertices are at distance exactly d. Motivated by the theory of network creation ... -
HAFLoop: An architecture for supporting highly adaptive feedback loops in self-adaptive systems
(Elsevier, 2020-04)
Article
Restricted access - publisher's policyMost of the current self-adaptive systems (SASs) rely on static feedback loops such as the IBM’s MAPE-K loop for managing their adaptation process. Static loops do not allow SASs to react to runtime events such as changing ... -
Smooth transitioning between two walking metaphors for virtual reality applications
(European Association for Computer Graphics (Eurographics), 2019)
Conference report
Open AccessVirtual navigation should be as similar as possible to how we move in the real world, however the limitations of hardware and physical space make this a challenging problem. Tracking natural walk is only feasible when the ...
