Enhanced EDX images by fusion of multimodal SEM images using pansharpening techniques

The goal of this paper is to explore the potential interest of image fusion in the context of multimodal scanning electron microscope (SEM) imaging. In particular, we aim at merging the backscattered electron images that usually have a high spatial resolution but do not provide enough discriminative information to physically classify the nature of the sample, with energy‐dispersive X‐ray spectroscopy (EDX) images that have discriminative information but a lower spatial resolution. The produced images are named enhanced EDX. To achieve this goal, we have compared the results obtained with classical pansharpening techniques for image fusion with an original approach tailored for multimodal SEM fusion of information. Quantitative assessment is obtained by means of two SEM images and a simulated dataset produced by a software based on PENELOPE.     

Supporting the design of mobile interactive artefacts

Current paper-based activities and practices are highly disseminated and intrinsic to our daily lives. Particular cases such as therapeutic and educational procedures, which rely strongly on paper-based artefacts (e.g., questionnaires, forms, manuals) assume special importance due to their critical content. However, their passiveness, limited interactivity, lack of adjustment, among other problems tend to obstruct personalization, hindering efficiency and limiting some users while achieving desired goals. This paper presents an environment that supports an easy and flexible design of tailored digital artefacts for mobile devices. The artefacts can be adjusted to the users’ needs, providing support to various purposes by coping with and enhancing different procedures. The environment integrates a set of configurable domain oriented guidelines that aid end-users through the creation of their personalized artefacts. It has been validated through three case studies by providing support to mobile learning, personal training and by offering means to achieve ubiquitous cognitive behavioural therapy.
