The distance between students’ concept image and quadrilateral object definition based on students’ mathematical ability

open access: yesAl-Jabar, 2022
Students learn mathematics through practical applications without applying it. Consequently, the concept images and definitions that students offer do not match.

Two-Dimensional Fuzzy Spatial Relations: A New Way of Computing and Representation

open access: yesAdvances in Fuzzy Systems, 2012
Fuzziness is found everywhere, in modeling spatial relations, fuzziness is found at object level as well as in relation semantics. Commonly, fuzzy topological relations are computed between fuzzy objects. Fuzziness in relation semantics is represented by

PREPROCESSING AND REGISTRATION OF MINISCOPE-BASED CALCIUM IMAGING OF THE RODENT BRAIN [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Microscopic imaging is central to the brain and cognition studies in animals and often requires advanced image processing. In vivo recordings on awake behaving animals require stabilization of the images as the tissue in the images undergoes non-rigid ...

Optimization of structural similarity in mathematical imaging [PDF]

open access: yesOptimization and Engineering, 2020
It is now generally accepted that Euclidean-based metrics may not always adequately represent the subjective judgement of a human observer. As a result, many image processing methodologies have been recently extended to take advantage of alternative visual quality measures, the most prominent of which is the Structural Similarity Index Measure (SSIM ...
