This paper describes an Augmented Reality (AR) system for the treatment of acrophobia. First, the technical characteristics of the first prototype are described. Second, the capacity of the immersive photography used in the AR system to provoke sense of presence in users is tested. Forty-one participants without fear of heights, walked around a staircase in both a real environment and an immers...

BACKGROUND Digital photography has simplified the process of capturing and utilizing medical images. The process of taking high-quality digital photographs has been recognized as efficient, timely, and cost-effective. In particular, the evolution of smartphone and comparable technologies has become a vital component in teaching and learning of health care professionals. However, ethical standar...

Purpose To investigate the feasibility of pediatric cataract monitoring and morphologic classification using slit lamp-adapted anterior segmental photography in a large cohort that included uncooperative children. Methods Patients registered in the Childhood Cataract Program of the Chinese Ministry of Health were prospectively selected. Eligible patients underwent slit-lamp adapted anterior s...

AIMS To evaluate the sensitivity and specificity of wide-field scanning laser ophthalmoscopy (WSLO) in the detection of referable diabetic eye disease, and to compare its performance with digital retinal photography. METHODS Patients enrolled into the study underwent non-mydriatic WSLO imaging, then single- and dual-field mydriatic digital retinal photography, and examination with slit lamp b...

We are just a few years away from celebrating the 200 anniversary of photography. The first permanent photographic record was made by Niépce in 1826, the view from his window at Le Gras. After many development cycles, including some periods of stagnation, photography is now experiencing an amazing period of growth. The changes that started in the mid 90’s and going into the next several years w...

Computational photography is an emergent multidisciplinary field that combines topics in optics, computer graphics, image and signal processing. The objective is usually the development of new algorithms or systems to capture images overcoming the limitations of conventional techniques. Images are not simply captured as 2D projections of a scene, they are rather coded before reaching the sensor...

The digital camera has brought a revolutionary shift in the nature of photography, sweeping aside more than 150 years of technology based on the weird and wonderful photochemistry of silver halide crystals. Curiously, though, the camera itself has come through this transformation with remarkably little change. A digital camera has a silicon sensor where the film used to go, and there’s a new di...

Fluoresing photography has become a prominent branch in opthalmology. During the last few years, it gives us dynamic infor-of circulation of the EYE and its pathologieal disorders.By passing the fluoresein through the retinal and choroidal vessels we are able to record the different typesand stages of disease which these are not exactly diagno-sed by ophthalmoscopy and founds photography.By flu...

In this book, we use the term domestic photography to describe the photographic activities of ordinary people taking and using images for non-professional purposes. Also, in our use of the term we focus on the kind of use in which photography is not a hobby as such but embedded in other activities. The word ‘domestic’ implies that the activities take place mainly in homes, and the home is the h...
