Interactive palette based colour editing applications have grown in popularity in recent years, but while many methods propose fast palette extraction techniques, they typically rely on the user to define the number of colours needed. In this paper, we present an approach that extracts a small set of representative colours from an image automatically, determining the optimal palette size without user interaction. Our iterative technique assigns a vote to each pixel in the image based...
Convolutional neural network (CNN)-based methods have achieved great success for single-image superresolution (SISR). However, most models attempt to improve reconstruction accuracy while increasing the requirement of number of model parameters. To tackle this problem, in this paper, we study reducing the number of parameters and computational cost of CNN-based SISR methods while maintaining the accuracy of super-resolution reconstruction performance. To this end, we introduce a novel network architecture for SISR, which strikes a good trade-off...
The effective design of visual computing systems depends heavily on the anticipation of visual attention, or saliency. While visual attention is well investigated for conventional 2D images and video, it is nevertheless a very active research area for emerging immersive media. In particular, visual attention of light fields (light rays of a scene captured by a grid of cameras or micro lenses) has only recently become a focus of research. As they may be rendered...
The phenomenon of voice-hearing: an interdisciplinary approach. An interview with Simon McCarthy-Jones.Simon McCarthy-Jones & Mathieu Frerejouan
The study of voice hearing has been traditionally kept within the limits of psychiatry field which, by reducing it to the pathological phenomenon of “auditory verbal hallucinations”, mainly focused on its neurobiological origins. However new approaches of voice hearing, coming from the field of psychology as well as of politics, have emerged recently. Simon McCarthy-Jones contributes to this effort of renewing and enlarging our understanding of voice hearing, by apprehending this phenomenon through its diversity,...
The Hybrid Placement model blends different contexts for practice-based learning: on-site, off-site, online and reflective practice. It has evolved in response to changed work practices in social work service delivery, necessitated by the Covid-19 pandemic. It aims to ensure quality learning opportunities, aligned with the CORU – Social Work Registration Board Domains of Proficiency, are maximised when it is not possible to attend the placement site full-time. This Practice Learning Resource has been developed by...
Photographs are characterized by different compositional attributes like the Rule of Thirds, depth of field, vanishing-lines etc. The presence or absence of one or more of these attributes contributes to the overall artistic value of an image. In this work, we analyze the ability of deep learning based methods to learn such photographic style attributes. We observe that although a standard CNN learns the texture and appearance based features reasonably well, its understanding of global...
Limited angular resolution is one of the main obstacles for practical applications of light fields. Although numerous approaches have been proposed to enhance angular resolution, view selection strategies have not been well explored in this area. In this paper, we study subsampling and reconstruction strategies for light fields. First, different subsampling strategies are studied with a fixed sampling ratio, such as row-wise sampling, column-wise sampling, or their combinations. Second, several strategies are explored to reconstruct...
Willibrord as a Political Actor Between Early Medieval Ireland, Britain and Merovingian Francia (658–739)Michel Summer
1000 Worte Forschung: PhD thesis in Medieval History, Department of History, Trinity College Dublin, ongoing
This research impact case study highlights the multiple impacts stemming from the 1641 Depositions Project. The document summarises how this flagship transdisciplinary digital humanities endeavour has engaged with publics inside and outside academia and transformed our understanding of how the controversial events of the mid-seventeenth century are recorded and remembered.
This paper summarises current industrial practices and standards promoting Human Factors Engineering (HFE) at design stage and revise them with an action research approached based on the concrete case studies performed during a European project called TOSCA. The paper highlights how HFE can significantly impact the costs and risk associated with a plant lifecycle and the current gaps and issues encountered. The gaps identified are used to guide industrial practices and standards towards a more...
