Microstructural analysis of non-woven fabrics using scanning electron microscopy and image processing. Part 1:Development and verification of the methods

This paper reports image analysis methods that have been developed to study the microstructural changes of non-wovens made by the hydroentanglement process. The validity of the image processing techniques has been ascertained by applying them to test images with known properties. The parameters in preprocessing of the scanning electron microscope (SEM) images used in image processing have been tested and optimized. The fibre orientation distribution is estimated using fast Fourier transform (FFT) and Hough transform (HT) methods. The results obtained using these two methods are in good agreement. The HT method is more demanding in computational time compared with the Fourier transform (FT) method. However, the advantage of the HT method is that the actual orientation of the lines can be concluded directly from the result of the transform without the need for any further computation. The distribution of the length of the straight fibre segments of the fabrics is evaluated by the HT method. The effect of curl of the fibres on the result of this evaluation is shown.

Microstructural analysis of non-woven fabrics using scanning electron microscopy and image processing. Part 2:Application to hydroentangled fabrics

The image analysis techniques developed in Part 1 to study microstructural changes in non-woven fabrics are applied to measure the fibre orientation distribution and fibre length distribution of hydroentangled fabrics. The results are supported by strength and modulus measurements using samples from the same fabrics. It is shown that the techniques developed can successfully be used to assess the degree of entanglement of hydroentangled fabrics regardless of their thickness.

Digital pathology and image analysis in tissue biomarker research

Digital pathology and the adoption of image analysis have grown rapidly in the last few years. This is largely due to the implementation of whole slide scanning, advances in software and computer processing capacity and the increasing importance of tissue-based research for biomarker discovery and stratified medicine. This review sets out the key application areas for digital pathology and image analysis, with a particular focus on research and biomarker discovery. A variety of image analysis applications are reviewed including nuclear morphometry and tissue architecture analysis, but with emphasis on immunohistochemistry and fluorescence analysis of tissue biomarkers. Digital pathology and image analysis have important roles across the drug/companion diagnostic development pipeline including biobanking, molecular pathology, tissue microarray analysis, molecular profiling of tissue and these important developments are reviewed. Underpinning all of these important developments is the need for high quality tissue samples and the impact of pre-analytical variables on tissue research is discussed. This requirement is combined with practical advice on setting up and running a digital pathology laboratory. Finally, we discuss the need to integrate digital image analysis data with epidemiological, clinical and genomic data in order to fully understand the relationship between genotype and phenotype and to drive discovery and the delivery of personalized medicine.

Mixed Messages: American Correspondences in Visual and Verbal Practices

Mixed Messages presents and interrogates ten distinct moments from the arts of nineteenth, twentieth and twenty-first century America where visual and verbal forms blend and clash. Charting correspondences concerned with the expression and meaning of human experience, this volume moves beyond standard interdisciplinary theoretical approaches to consider the written and visual artwork in embodied, cognitive, and contextual terms.

Offering a genuinely interdisciplinary contribution to the intersecting fields of art history, avant-garde studies, word-image relations, and literary studies, Mixed Messages takes in architecture, notebooks, poetry, painting, conceptual art, contemporary art, comic books, photographs and installations, ending with a speculative conclusion on the role of the body in the experience of digital mixed media. Each of the ten case studies explores the juxtaposition of visual and verbal forms in a manner that moves away from treating verbal and visual symbols as operating in binary or oppositional systems, and towards a consideration of mixed media, multi-media and intermedia work as brought together in acts of creation, exhibition, reading, viewing, and immersion. The collection advances research into embodiment theory, affect, pragmatist aesthetics, as well as into the continuing legacy of romanticism and of dada, conceptual art and surrealism in an American context.

‘Twenty-six things at once’: Pragmatic perspectives on Frank O’Hara and Norman Bluhm’s Poem-Paintings

Created over a couple of Sunday mornings in the Fall of 1960, the twenty-six collaborative Poem-Paintings of the artist Norman Bluhm and the poet Frank O'Hara represent what Bluhm later called a spontaneous 'conversation' between the painter and the poet. In this essay, Catherine Gander adopts a number of pragmatist positions to reconsider these overlooked works as essential examples of verbal-visual interaction that extend their 'conversation' to greet and involve us in a relationship that is at once interpersonal, integrated, and embodied. The works, Gander argues, constitute what John Dewey terms 'art as experience'; in their back and forth exchange of verbal and visual gesture, abstraction and denotation, the Poem-Paintings are the 'cumulative continuity' of 'the process of living', dramatising the shifting, spontaneous and multiple dimensions of interpersonal conversation, and in so doing, indicating a new path toward interconnective and equal exchange between word and image.

To fasten words again to visible – and invisible – things

In this extended introductory essay, Catherine Gander and Sarah Garland suggest new ways of looking at the correspondences between visual and verbal practices to consider their material and conceptual connections in a specifically American set of histories, contexts and interpretive traditions. Tracing a lineage of experiential philosophy that is grounded in the overturning of a Cartesian mind/body split, the authors argue for pluralistic perspectives on intermedial innovations that situate embodied and imaginative reader-viewer response as vital to the life of the artwork. Gander and Garland chart two main strands to this approach: the pragmatist strain of American aesthetics and social politics, rooted in the essays of transcendentalist Ralph Waldo Emerson and emanating from the writings of John Dewey and William James; and the conceptualist strain of French-American Marcel Duchamp, whose ground-breaking ideas both positioned the artwork as a phenomenological construction and liberated the artist from established methods of practice and discourse. The ‘imagetext’ (after W. J. T. Mitchell) is therefore, argue Gander and Garland, a site consisting of far more than word and image – but a living assemblage of language, idea, thing, cognition, affect and shared experience.

Streaming Elements for FPGA Signal and Image Processing Accelerators

Field programmable gate array devices boast abundant resources with which custom accelerator components for signal, image and data processing may be realised; however, realising high performance, low cost accelerators currently demands manual register transfer level design. Software-programmable ’soft’ processors have been proposed as a way to reduce this design burden but they are unable to support performance and cost comparable to custom circuits. This paper proposes a new soft processing approach for FPGA which promises to overcome this barrier. A high performance, fine-grained streaming processor, known as a Streaming Accelerator Element, is proposed which realises accelerators as large scale custom multicore networks. By adopting a streaming execution approach with advanced program control and memory addressing capabilities, typical program inefficiencies can be almost completely eliminated to enable performance and cost which are unprecedented amongst software-programmable solutions. When used to realise accelerators for fast fourier transform, motion estimation, matrix multiplication and sobel edge detection it is shown how the proposed architecture enables real-time performance and with performance and cost comparable with hand-crafted custom circuit accelerators and up to two orders of magnitude beyond existing soft processors.
