Diabetic retinopathy screening experiences since 1978

If the increasing prevalence of Diabetes continues, it will become the next world epidemic, particularly in remote Australian Indigenous communities.

The Lions Eye Institute, Perth, Western Australia first started screening for diabetic retinopathy (a sight threatening complication of diabetes) in 1978. Screening involves imaging the retina of the eye and interpretation by trained medical personnel. Until recently, images in remote areas have used Polaroid film. Digital technology is now available in remote and rural communities via medium speed satellite links. A discussion on training aboriginal health workers to operate non-mydriatic retinal cameras and the problems associated with moving delicate instruments over rough terrain will be discussed along with the problems associated with digital imaging in this hostile environment.

Although the number of diabetics screened in remote areas are relatively small due to travel times and community sizes, our results show a continuing need for this service with results ranging from 20%-40% of those screened showing some ophthalmic pathology.

Victoria Police

The Big Picture

Victoria Police is the first jurisdiction in Australia to trial camera technology that can capture an entire crime scene in a single image. The addition of two panoramic cameras has enabled investigators to photograph and analyse 360-degree views of crime scenes and allow for greater security planning ahead of major events.
These cameras have been used in anti-terrorism work during the Commonwealth Games and for serious crime scenes. The camera is mounted on a carbon fibre tripod and uses a battery as the power supply. A laptop computer is wired to the tripod and allows viewing of the image. The camera takes a 30-second preview scan, and then a full-circle seamless image arrives on the laptop screen. Depending on light, the actual scan can take between one and 10 minutes to record the scene.

Once the image has been downloaded, software programs are used to turn the panoramic image into a cylinder or 3D cube before viewing. Still images, maps, plans and video footage can be added to build a complete file that becomes fully interactive and navigable.

Back to the Future?

I have taught photography since 1982 so the offer of a return to full time employment in the industry that had given my life meaning at the tender age of 17 was an opportunity I could not refuse. Eleven years spent as a press photographer with Queensland Newspapers, prior to the News Limited takeover in 1983, had provided me with the requisite practical skills to enlist as an instructor with TAFE in Queensland and the subsequent jump to lecturer with Griffith University ten years later. I have kept close links with the industry for the last 24 years, providing students with ample work experience and job opportunities. The thought of working with many of my own graduates in the roll of Picture Editor of Australia’s second largest circulation newspaper and the chance to contribute to the look and content of the paper was a dream come true. Or was it?

Infrared video eye-tracking for understanding visual attention in subjects attempting to forge signatures.

Signatures are the product of a complex motor program used to authenticate or identify an author. Simulating or forging signatures is undertaken by those wishing to steal an author’s identity. A Tobii x50 video eye tracker and Panasonic NVGS17 scene camera were used to record both eye movements and handwriting whilst subjects forged either continuous-stylised or text-based-alphabetical signatures. Data was synchronised to allow an analysis of the particular features that subjects paid attention to in target signatures, whilst coordinating the motor control of hand movements to produce accurate forgeries. By comparing between different styles of signature (stylised or alphabetical) it was possible to quantify the load on human working memory for conducting forgeries, and thus provide strong quantitative evidence for why subjects produce line fluency errors that can be used by Forensic Document Examiners to detect forged signatures.1 This newly devised technique thus allows a white box approach to quantifying how visual attention is deployed in human subjects for important security tasks like signature evaluation.

The Old meets the New: The Daguerreotype Hologram

The first practical photographic process, the daguerreotype of 1839, used a thin coating of silver iodide on the surface of a silver plate to capture the image. The process was slow but was capable of resolving fine detail. The hologram, invented in the 1960s, relies on the ability of a thin coating of a fine-grain photographic emulsion to capture fine detail. The question arises - would it be possible to use a daguerreotype plate to capture a holographic image? This paper discusses the problems encountered and the eventual successful outcome - the first ever.

3D Technology and the 21st Century Clinical Photographer

In 2004 the Royal Children's Hospital was fortunate enough to take a major step towards assuming a leadership position in 3D technology with the generous gift from the Muriel and Les Batten Foundation. This allowed for the purchase of a sophisticated 3D imaging system, which is the first of its kind in Australasia.  This camera has allowed for more accurate imaging, diagnosis and treatment planning at the hospital in only its second year and has also opened the door for collaboration with other Australasian centres as well as centres in North America and Europe .The 3D imaging system has had direct patient impact and has profound implications upon the hospital’s ability to provide world’s best care to Victorian children in 3D imaging, diagnosis, treatment planning and outcomes analysis.

I fake things for a living! Adventures in a self employed digital business

A brief adventure through the possibilities for digital imaging and the self employed. There isn't a word for what I do. 3D visualisation, photography, retouching, Photoshop artist, animation, visual effects, video production, editing. It depends on the project. So what do I tell Mum I do for a living? I graduated RMIT Scientific Photography at the end of 1992, the last class before they wheeled in a few dozen Apple Macs. Since then, I have been catching up. How did my degree help me? The technology changes, but the principles don't.

Issues of copyright affecting photography in medicine, science and education

Whether you are corporate or industrial; scientific or medical; freelance or employed, photographers create many images that have impact and value in the marketplace.

This presentation will inform photographers about the interface between picture research, copyright clearance in Australia and publication. It will share real experiences and ideas of issues for all working photographers.

The long line from France: experiences in distance education

Lloyd Godman has been teaching on line for the past 2 years – This talk presents a personal perspective from real life experience that out lines some disadvantages and advantages including teaching online from the South of France during the southern hemisphere winter. It also presents future directions in this area from the convergence of technology.
