Comprehensive analysis of distance and similarity measures for Wi-Fi fingerprinting indoor positioning systems
(Elsevier, 2015)
Recent advances in indoor positioning systems led to a business interest in those applications and services where a precise localization is crucial. Wi-Fi fingerprinting based on machine learning and expert systems are ...
A Study on How Food Colour May Determine the Categorization of a Dish: Predicting Meal Appeal from Colour Combinations
(World Scientific Publishing, 2022-12)
A person’s preference to select or reject certain meals is influenced by several aspects, including colour. In this paper, we study the relevance of food colour for such preferences. To this end, a set of images of meals ...
Spatial reasoning about qualitative shape compositions. Composing Qualitative Lengths and Angles
(Springer, 2020-06-24)
Shape composition is a challenge in spatial
reasoning. Qualitative Shape Descriptors (QSD) have proven to be rotation and location invariant, which make
them useful in spatial reasoning tests. QSD uses qualitative ...
Sketch Retrieval based on Qualitative Shape Similarity Matching: Towards a Tool for Teaching Geometry to Children
(IOS Press, 2015)
An approach for a query-by-sketch system on qualitative
shape information for image retrieval in databases is proposed
and evaluated. The use of qualitative methods for
shape description allows the gathering of semantic ...
Special issue on pattern recognition and cognitive assistants
(Elsevier ScienceDirect, 2020-03-12)
This special issue proposes a space for researchers to discuss the challenges of bridging pattern recognition and cognitive assistants. This bridge was travelled in both sides. From one side, how pattern recognition methods ...
Describing images using qualitative models and description logics
(Taylor & Francis, 2011)
Our approach describes any digital image qualitatively by detecting regions/objects inside it and describing their visual characteristics (shape and colour) and their spatial characteristics (orientation and topology) by ...
Towards a model of creative understanding: deconstructing and recreating conceptual blends using image schemas and qualitative spatial descriptors
(Springer, 2020)
Computational models of novel concept understanding and creativity are addressed in this paper from the viewpoint of conceptual blending theory (CBT). In our approach, a novel, unknown concept is addressed in a communication ...
A model-driven transformation approach for the modelling of processes in clinical practice guidelines
(Elsevier, 2023)
Clinical Practice Guidelines (CPGs) include recommendations aimed at optimising patient care, informed by a
review of the available clinical evidence. To achieve their potential benefits, CPG should be readily available
at ...
Special issue on logics and artificial intelligence
(Oxford University Press, 2020-01-18)
There is a significant range of ongoing challenges in artificial intelligence (AI) dealing with reasoning, planning, learning, perception and cognition, among others. In this scenario, many-valued logics emerge as one of ...
A model for colour naming and comparing based on conceptual neighbourhood. An application for comparing art compositions
(Elsevier, 2015)
A computational model for Qualitative Colour Description, named the QCD model, is defined using the Hue, Saturation and Luminance colour space. This model can name rainbow colours, pale, light and dark colours, and colours ...
