Geometric correction of historical Arabic documents

Geometric deformations in historical documents significantly influence the success of both Optical Character Recognition (OCR) techniques and human readability. They may have been introduced at any time during the life cycle of a document, from when it was first printed to the time it was digitised by an imaging device. This Thesis focuses on the challenging domain of geometric correction of Arabic historical documents, where background research has highlighted that existing approaches for geometric correction of Latin-script historical documents are not sensitive to the characteristics of text in Arabic documents and therefore cannot be applied successfully. Text line segmentation and baseline detection algorithms have been investigated to propose a new more suitable one for warped Arabic historical document images. Advanced ideas for performing dewarping and geometric restoration on historical Arabic documents, as dictated by the specific characteristics of the problem have been implemented.In addition to developing an algorithm to detect accurate baselines of historical printed Arabic documents the research also contributes a new dataset consisting of historical Arabic documents with different degrees of warping severity.Overall, a new dewarping system, the first for Historical Arabic documents, has been developed taking into account both global and local features of the text image and the patterns of the smooth distortion between text lines. By using the results of the proposed line segmentation and baseline detection methods, it can cope with a variety of distortions, such as page curl, arbitrary warping and fold

Body of glass: cybernetic bodies and the mirrored self

This thesis examines the ontology of the cyborg body and the politics inherent to cultural manifestations of that image, and focuses on the links between glass and human-machine integration, while tracing the dangerous political affinities that emerge when such links are exposed. In the first chapter, the cyborg’s persistent construction as a cultural Black Box is uncovered using the theories of Bruno Latour and W. Ross Ashby. It examines why the temptation to explore the cyborg solely through close readings of contemporary incarnations leads only to confusion and misreading. The second chapter builds on the work of the first by placing the cyborg within its proper historical context, and provides a detailed examination of the period in which the cyborg was not only named, but also transformed into a physical possibility with an existent political agenda. It then investigates the phallogocentricity, hyper-masculinity, and inherent racism of the cyborg body, and demonstrates how representations of human-machine integration reinforce the pre-existing racist, hetero-normative, patriarchal hegemony of the Cold War. The discussion then explores the issue of the emergent property in the cyborg body; specifically, the figure’s persistent construction as a ‘body of glass.’ It demonstrates how cyborgs are not only associated with objects like the mirror, but also how that figure is tied to visual motifs such as the double or doppelganger. Accordingly, the theories of Jacques Lacan are employed to elucidate the issues that arise when one of the most pervasive images in Western culture also doubles as a reflector. The final chapter seeks to expand upon the framework provided by Lacan, and examines the cyborg not as a mirror, but as a portal. Subsequently, this section challenges not only the cyborg’s current status as a posthuman figure, but also current theoretical assumptions which frame the cyborg as the point of transition from humanism to posthumanism

Rhapsodic Objects

Circulation and imitation of cultural products are key factors in shaping the material world.The contributions explore how technical knowledge, immaterial desires, and political agendas impacted the production and consumption of visual and material culture in different times and places. They map a new a multidirectional market for cultural goods in which the source countries can be positioned at the center
