Distance-driven fusion of gait and face for human identification in video

Gait and face are two important biometrics for human identification. Complementary properties of these two biometrics suggest fusion of them. The relationship between gait and face in the fusion is affected by the subject-to-camera distance. On the one hand, gait is a suitable biometric trait for human recognition at a distance. On the other hand, face recognition is more reliable when the subject is close to the camera. This paper proposes an adaptive fusion method called distance-driven fusion to combine gait and face for human identification in video. Rather than predefined fixed fusion rules, distance-driven fusion dynamically adjusts its rule according to the subject-to-camera distance in real time. Experimental results show that distance-driven fusion performs better than not only single biometric, but also the conventional
static fusion rules including MEAN, PRODUCT, MIN, and MAX.

Individual discriminative subspace for face recognition under uncontrolled conditions

Most face recognition (FR) algorithms require the face images to satisfy certain restrictions in various aspects like view angle, illumination, occlusion, etc. But what is needed in general is the techniques that can recognize any face images recognizable by human beings. This paper provides one potential solution to this problem. A method named Individual Discriminative Subspace (IDS) is proposed for robust face recognition under uncontrolled conditions. IDS is the subspace where only the images from one particular person converge around the origin while those from others scatter. Each IDS can be used to distinguish one individual from others. There is no restriction on the face images fed into the algorithm, which makes it practical for real-life applications. In the experiments, IDS is tested on two large face databases with extensive variations and performs significantly better than 12 existing FR techniques.

Positioning the case to tell the story: developing the narrative or presentational account

This paper is drawn from a doctoral study (in its final stages) about the use and adoption of information and communication technologies (ICTs) to enhance the face-to-face teaching by six academic staff, who represent different disciplines and different campus locations, in a large, regional university in Australia. A collective case study was adopted as the framework for the study, and field data comprised semi-structured interviews, curriculum guides, teaching and learning resources, websites, and included results of a Teaching Practices Inventory completed by each of the research participants.

Case study is a popular choice of qualitative researchers. There are numerous examples in the literature of case study as the vehicle for examining issues concerning teachers' use of new technologies in teaching and learning. This paper situates the research study in the qualitative, interpretative research paradigm, and matches the choice of case as the research strategy to accepted characteristics of good case studies. The focus of the paper then moves to the practical, yet difficult problem faced by the researcher of ways of presenting the case, seeking a balance between the demands of prescribed, social scientific writing for an academic audience, and the need to create texts that are interesting, vital and that “make a difference”(Richardson, 2003). Using a sample case from the study, the paper examines approaches to constructing meaning from the field data to create the narrative or presentational account and, ultimately, the research text.

Screening Michael Jackson's face : reading Martin Bashir's living with Michael Jackson

The screening of Martin Bashir's Living with Michael Jackson on Australian television elicited a phenomenal amount of interest in the news media, at water coolers and on the Internet. Much of the response in the Australian print media was critical of Bashir's representation of Jackson, as well as denouncing Jackson as sad victim, warped predator and allround freakshow. This article considers these interpretations to argue that the production and consumption of 'wacko Jacko' is underpinned by the increasing instability of the natural in an age of information technologies, as well as the collapse of boundaries between documentary and fictional entertainment forms.

Bullying affects us too: parental responses to bullying at kindergarten

Preschool age children are often thought of as too young to be able to engage in bullying behaviours. However, when it does occur, there are ramifications not only for the child but also for parents and siblings. This article explores this issue by reporting on an exploratory study involving interviews with four parents whose child had experienced bullying in a Victorian kindergarten. Parents reported a range of responses, including anger, guilt for not protecting their child, and powerlessness in the face of denial from kindergarten staff that their child had been bullied. Being unable to access information about bullying among preschool children which might validate their experiences, reinforced the sense of isolation these parents experienced. Further research which explores the needs of family members of children bullied in the kindergarten (prior to school) setting is needed.

Classification of face images using local iterated function systems

There has been an increasing interest in face recognition in recent years. Many recognition methods have been developed so far, some very encouraging. A key remaining issue is the existence of variations in the input face image. Today, methods exist that can handle specific image variations. But we are yet to see methods that can be used more effectively in unconstrained situations. This paper presents a method that can handle partial translation, rotation, or scale variations in the input face image. The principal is to automatically identify objects within images using their partial self-similarities. The paper presents two recognition methods which can be used to recognise objects within images. A face recognition system is then presented that is insensitive to limited translation, rotation, or scale variations in the input face image. The performance of the system is evaluated through four experiments. The results show that the system achieves higher recognition rates than those of a number of existing approaches.

Adaptive fusion of gait and face for human identification in video

Most work on multi-biometric fusion is based on static fusion rules which cannot respond to the changes of the environment and the individual users. This paper proposes adaptive multi-biometric fusion, which dynamically adjusts the fusion rules to suit the real-time external conditions. As a typical example, the adaptive fusion of gait and face in video is studied. Two factors that may affect the relationship between gait and face in the fusion are considered, i.e., the view angle and the subject-to-camera distance. Together they determine the way gait and face are fused at an arbitrary time. Experimental results show that the adaptive fusion performs significantly better than not only single biometric traits, but also those widely adopted static fusion rules including SUM, PRODUCT, MIN, and MAX.

The changing face of the Australian teaching profession : new generations and new ways of working and learning

Today’s workforce is characterised by an increasing mix of people with varying career aspirations, work motivators and job satisfiers. This paper discusses the intergenerational nature of today’s workforce, which is currently dominated by the age groups commonly referred to as Baby Boomers and Generation X. The Baby Boomers defined and redefined work during the last quarter of the twentieth century, but as they track towards retirement, GenXers’ valued work patterns and their career and life aspirations are increasingly dominating. This paper draws on a body of literature about a younger generation of workers and the current world of work in today’s knowledge society, and discusses possible implications for the teaching profession, particularly for attracting and retaining young people as teachers.

The changing face of literacy policy in Victoria

In the transition from the twentieth to the twenty-first century, literacy has undergone a fundamental change in the shift from page to screen as the dominant basis for communication. In a communications environment characterised by multimodality - integration of modes of linguistic, visual, audio, gestural and spatial modes of meaning - young people require a broadened repertoire of literacy capacities.
Educational authorities with responsibility for literacy policy have responded in terms of curriculum, and assessment advice within a context of rapidly changing forms of multimodal communication. This paper details the early twenty-first century response of one educational authoríty, the Department of Education, Victoria, in reviewing early years literacy curriculum and assessment in light of the rapid developments in digital communications.

Windfarms, powerlines and phone masts : the changing face of stigma

Previous research has identified varying degrees of stigma attached to high voltage overhead transmission lines (HVOTLs) depending upon characteristics such as visibility, size, location and the potential impact on house value. In addition to HVOTLs there are other common types of infrastructure, namely mobile phone towers and windfarms, that are also large highly visible
structures and can exhibit similar characteristics. These similarities include varying levels of visibility from properties in the immediate vicinity, a high general profile in society and varying perceptions from surrounding residents about possible side effects. This research broadens the framework originally developed to study HVOTLs to encompass mobile phone towers and windfarms. It undertakes a literature review of research in this area and proposes a research methodology for identifying and quantifying the varying levels of stigma attached to these three forms of infrastructure. The final results will enable the resulting effect on property values to be better understood, and assist developers to fully understand their effect on devaluing land prices.

A new screen face for public service broadcasting

The contemporary broadcasting industry is characterised by technological and social change, it is increasingly competitive, and the media industry is fragmenting. New services need not necessarily compete with existing free-to-air broadcasting but could act as further incentive for audiences to invest in new equipment. New equipment will be necessary in the future as set out under the Television Broadcasting Services (Digital Conversion) Act 2000 (Cth), before the planned switch-off of analogue broadcasts planned for this year but now likely to be 2013. By then, however, audiences might already have migrated to the online environment for television and radio content as well as other services. Those that produce and deliver programs via free-to-air broadcasting need to consider what audiences do with new media in order to engage them. This will be an ongoing process as technology and audience expectations continue to change. Against such a background, this article examines how Australia’s public broadcasters are responding to the new media environment. It will consider their interactive online programs and services with specific analysis of ABC’s new ‘iView’ and ‘ABC Fora’ which offer content on-demand. It will also examine SBS online initiatives. I wish to argue that the new media offer public broadcasters new prospects to provide forums and spaces for education, entertainment, public discussion and interaction online.

It was an experience that totally blew up in my face : Steve Railsback and Turkey shoot

The schlock horror film Turkey Shoot is widely regarded as one of the most disreputable Australian exploitation titles in a genre already well noted for controversy. This short article frames the controversies that surround the film from production to critical reception, which sets the scene for an interview by Mark Harley with the film's star Steve Railsback, who reflects on the movie's production, his role, the controversy and the film's reception.

Government regulation to promote healthy food environments : a view from inside state governments

Food policy interventions are an important component of obesity-prevention strategies and can potentially drive positive changes in obesogenic environments. This study sought to identify regulatory interventions targeting the food environment, and barriers/facilitators to their implementation at the Australian state government level. In-depth interviews were conducted with senior representatives from state/territory governments, statutory authorities and non-government organizations (n = 45) to examine participants’ (i) suggestions for regulatory interventions for healthier food environments and (ii) support for pre-selected regulatory interventions derived from a literature review. Data were analysed using thematic and constant comparative analyses. Interventions commonly suggested by participants were regulating unhealthy food marketing; limiting the density of fast food outlets; pricing reforms to decrease fruit/vegetable prices and increase unhealthy food prices; and improved food labelling. The most commonly supported preselected interventions were related to food marketing and service. Primary production and retail sector interventions were least supported. The dominant themes were the need for whole-of-government and collaborative approaches; the influence of the food industry; conflicting policies/agenda; regulatory challenges; the need for evidence of effectiveness; and economic disincentives. While interventions such as public sector healthy food service policies were supported by participants, marketing restrictions and fiscal interventions face substantial barriers including a push for deregulation and private sector opposition.

Reshaping dominant stories : a poststructuralist approach to online role play

Online role play is an increasingly popular teaching/learning technique in higher education (Wills & McDougall 2009) but there has been little research into ways a poststructuralist approach may be supported in this format. This paper describes two very different means of incorporating a poststructuralist approach into role plays in higher education to problematise dominant assumptions in the language and content of the subject matter. The first method was a series of interventions in a face-to-face role play in which medical students practised consultations with adolescent school students. The consultations were interrupted repeatedly with activities designed to interrogate assumptions and the school students acted as coaches to improve the medical students' technique. Although this role play was performed face-to-face, some of its activities may be redeveloped to suit an online role-playing format. The second method was a feature of an online role play involving Middle-East politics and journalism students, in which daily online newspapers provided a reflecting and distorting mirror to the political events simulated by the politics students. Indications of ways in which the two methods produced changes in understanding were gathered using a mixture of qualitative and quantitative methods: questionnaires, focus groups, interviews, participant observation and analysis of online discussions and artefacts.

Efficient tensor based face recognition

This paper addresses the limitation of current multilinear PCA based techniques, in terms of pro- hibitive computational cost of testing and poor gen- eralisation in some scenarios, when applied to large training databases. We define person-specific eigen-modes to obtain a set of projection bases, wherein a particular basis captures variation across light- ings and viewpoints for a particular person. A new recognition approach is developed utilizing these bases. The proposed approach performs on a par with the existing multilinear approaches, whilst sig- nificantly reducing the complexity order of the testing algorithm.
