Model-based character recognition in low resolution

We propose a combined character separation and recognition approach for low-resolution images of alphanumeric text. By synthesising the image formation process a set of low-resolution templates is created for each character. Cluster algorithms and normalised cross-correlation are then applied to match these templates and thereby allowing both character separation and recognition to be achieved at the same time. Thus characters are recognised using their low-resolution appearance only without applying image enhancement methods. Experiments showed that this approach is able to recognise low-resolution alphanumeric text of down to 5 pixels in size.

Portable form filling assistant for the visually impaired

The filling of printed forms has always been an issue for the visually impaired. Though optical character recognition technology has helped many blind people to ‘read’ the world, there is not a single device that allows them to fill out a paper-based form without a human assistant. The task of filling forms is however an essential part of their daily lives, for example, for access to social security or benefits. This paper describes a solution that allows a blind person to complete paper-based forms, pervasively and independently, using only off-the-shelf equipment including a Smartphone, a clipboard with sliding ruler, and a ballpoint pen. A dynamic color fiduciary (point of reference) marker is designed so that it can be moved by the user to any part of the form such that all regions can be “visited”. This dynamic color fiduciary marker is robust to camera focus and partial occlusion, allowing flexibility in handling the Smartphone with embedded camera. Feedback is given to the blind user via both voice and tone to facilitate efficient guidance in filling out the form. Experimental results have shown that this prototype can help visually impaired people to fill out a form independently.

Recognizing and celebrating Xhosa traditional music in South Africa

The recognition and celebration of Indigenous Knowledge Systems (IKS) as a way forward to promote democracy and inclusivity continues to be part of South Africa's nation building process. One effective platform for this to take place is through community music making as music making in Africa is a way of life. Since democracy in 1994 many initiatives were set up to explore and foster traditional music. This paper presents a brief contextualization of IKS, identity and community music making. It reports on the a Xhosa music research project (2004-2006) as an ethnographic study which is descriptive and interpretive as a holistic cultural portrait. Participants in the project included post-graduate music students, community culture bearers and academics. Only some significant aspects of the Xhose music project at the University of Fort Hare will be reported on. We contextualize the recognition and celebration of IKS within the parameters of the music and the culture of the amaMpondo within the Xhosa people. The paper specifically focuses on the ritual life of the amaMpondo. It also describes the indigenous bow instruments of the Uhadi and Umrhubhe as unique examples of South Africa's traditional music. As this initiative proved a worthy undertaking, we challenge whether such a project could strengthen local IKS elsewhere and be a pathway for tertiary institutions to engage effectively with local community music practitioners in order to prepare students effectively as holistic music educators.

So much more than just the music : Australian pre-service music teacher education students’ attitudes to artists-in-schools

Contemporary Australia is a country of ongoing migration and increasing cultural diversity which is reflected in its arts practices. This article considers the views held by Australian pre-service music education student teachers and their tertiary music educators about their perceptions concerning artists-in-schools programs in school music. This discussion reports on data collected for a study undertaken in Melbourne, Victoria, Intercultural Understandings of Pre-Service Music Education Students (2005–2009). Fifty-three interviews were analyzed using interpretative phenomenological analysis. The findings provide insight into teachers’ recognition of the need for artists-in-schools programs. In particular the ways in which teachers can link theory to practice, fill in omissions in their own knowledge, skills and understandings, and heighten student understandings of multicultural musics. The promotion and provision of multicultural music education is essential at all levels of education. This can be achieved by the inclusion of diverse culture bearers, artists-in-schools, and community engagement to work with both teachers and their students.

A novel defect detection and identification method in optical inspection

Optical inspection techniques have been widely used in industry as they are non-destructive. Since defect patterns are rooted from the manufacturing processes in semiconductor industry, efficient and effective defect detection and pattern recognition algorithms are in great demand to find out closely related causes. Modifying the manufacturing processes can eliminate defects, and thus to improve the yield. Defect patterns such as rings, semicircles, scratches, and clusters are the most common defects in the semiconductor industry. Conventional methods cannot identify two scale-variant or shift-variant or rotation-variant defect patterns, which in fact belong to the same failure causes. To address these problems, a new approach is proposed in this paper to detect these defect patterns in noisy images. First, a novel scheme is developed to simulate datasets of these 4 patterns for classifiers' training and testing. Second, for real optical images, a series of image processing operations have been applied in the detection stage of our method. In the identification stage, defects are resized and then identified by the trained support vector machine. Adaptive resonance theory network 1 is also implemented for comparisons. Classification results of both simulated data and real noisy raw data show the effectiveness of our method.

Paths of professional development in music therapy: training, professional identity and practice

Music therapy is listed as a profession in the EU Regulated Professions Database. This has assisted the next steps towards recognition in relevant countries and regions. The author’s experience as an academic leader in music therapy training over more than two decades is used to reflect on the profession of music therapy within Europe through interrogation of concepts underpinning professional identity, training, and professional practice. Potential tensions between recognition and regulation of healthcare professions are presented and discussed. As all practice takes place in context, balancing training needs between techniques and skills, systemic national and regional policy, and institutional knowledge is crucial. Achieving this balance is not easy but is key to successful growth of practitioner knowledge, seeding student’s curiosity about context and systems from the dawn of training.

Optical actuation of inorganic/organic interfaces: comparing peptide-azobenzene ligand reconfiguration on gold and silver nanoparticles

Photoresponsive molecules that incorporate peptides capable of material-specific recognition provide a basis for biomolecule-mediated control of the nucleation, growth, organization, and activation of hybrid inorganic/organic nanostructures. These hybrid molecules interact with the inorganic surface through multiple noncovalent interactions which allow reconfiguration in response to optical stimuli. Here, we quantify the binding of azobenzene-peptide conjugates that exhibit optically triggered cis-trans isomerization on Ag surfaces and compare to their behavior on Au. These results demonstrate differences in binding and switching behavior between the Au and Ag surfaces. These molecules can also produce and stabilize Au and Ag nanoparticles in aqueous media where the biointerface can be reproducibly and reversibly switched by optically triggered azobenzene isomerization. Comparisons of switching rates and reversibility on the nanoparticles reveal differences that depend upon whether the azobenzene is attached at the peptide N- or C-terminus, its isomerization state, and the nanoparticle composition. Our integrated experimental and computational investigation shows that the number of ligand anchor sites strongly influences the nanoparticle size. As predicted by our molecular simulations, weaker contact between the hybrid biomolecules and the Ag surface, with fewer anchor residues compared with Au, gives rise to differences in switching kinetics on Ag versus Au. Our findings provide a pathway toward achieving new remotely actuatable nanomaterials for multiple applications from a single system, which remains difficult to achieve using conventional approaches.
