This article contains a survey of recent debates in the philosophy of photography, focusing on aesthetic and epistemic issues in particular. Starting from widespread notions about automatism, causality and realism in the theory of photography, the authors ask whether the prima facie tension between the epistemic and aesthetic embodied in oppositions such as automaticism and agency, causality an...

PURPOSE A pilot study of human neural retinal transplantation was undertaken to investigate three major issues: whether a safe surgical procedure could be devised for transplantation of neural retinal tissue into the subretinal space, whether the transplant would be accepted in the subretinal space, and whether an improvement in vision could be achieved. METHODS Eight patients with bare light...

Retinoblastoma is the most common primary intraocular tumor in children. The first sign that is often reported by parents is the appearance of recurrent leukocoria (i.e., "white eye") in recreational photographs. A quantitative definition or scale of leukocoria--as it appears during recreational photography--has not been established, and the amount of clinical information contained in a leukoco...

We contribute a qualitative investigation of how teens with visual impairments (VIP) access smartphone photography, from the time they take photos through editing and sharing them on social media. We observed that they largely want to engage with photos visually, similarly to their sighted peers, and have developed strategies around photo capture, editing, sharing, and consumption that attempt ...

introduction: anthropometry (morphometry of the human) is measurement of linear and angular dimensions of the human body. since the anthropometric parameters which are based on age, sex, geographical location and ethnic characteristics of the human species are different, therefore, anthropometric studies of population by age and sex should be done separately. methods: in this study, anthropomet...

This article discusses spatial experience in games, in relation to other media. A brief review of some classic works on spatial experience in literature, photography, cinema and television is presented. A theoretical framework composed of three ‘types of space’ is used for an analysis of a hypothetical simplified gameplay. As a result, the spatial experience of games is understood as a dynamic ...

We present a 3D photography method that generates a texture-mapped three-dimensional model of a scene computed from multi-view calibrated two-dimensional photographs. Our approach first performs probabilistic space carving, which results in a 3D grid of voxel probabilities that describe the likelihood of a voxel existing in the model. We then employ a three-dimensional geodesic active surface t...

In this paper, we present a Self-Avoiding Polygon (SAP) model for describing and detecting complex gable rooftops from nadir-view aerial imagery. We demonstrate that a broad range of gable rooftop shapes can be summarized as self-avoiding polygons, whose vertices correspond to roof corners. The SAP model, defined over the joint space of all possible SAPs and images, combines the shape prior emb...

We introduce two fourth-order regularization methods that remove geometric noise without destroying significant geometric features. These methods leverage ideas from image denoising and simplification of high contrast images in which piecewise affine functions are preserved up to infinitesimally small transition zones. We combine the regularization techniques with active contour models and appl...
