The addition of patient photographs to radiology studies has a number of possible benefits including reducing wrong-patient errors [1, 2], providing context to the radiologist for interpretation, and reconnecting the radiologist with the patient. By providing the radiologist with photographs corresponding to radiology studies, wrong-patient errors can be identified readily when comparative stud...

Because photographs capture an individual at a moment in time, they contain fleeting features as well as more stable ones. Caricature line drawings, however, include stable features and emphasize distinctive ones. As such, caricatures are closer to schematic memory representations than are photographs. Three experiments using faces of public figures test the hypothesis that caricatures yield be...

We describe a simple, economical, and highly practical technique for taking digital photographs of specimens visualized through a light microscope. Most models of light microscope and compact digital camera, and even some cameraphones, can be used. The technique is quick to learn and can easily be performed in a resource-poor setting. It can be used to assist with diagnosis in remote areas and ...

that refraction by a lens is not indispensable to the formation of a photographic image. The effective range of fluorescent and actinic X-rays is limited to two or three feet, and for this distance from a camera a "pinhole" in a metal disc does quite as well in ordinary photography as any lens or combination of lenses, so far as pictorial effect and clearness are concerned, provided the exposur...

Material replacement has wide application throughout the entertainment industry, particularly for postproduction make-up application or wardrobe adjustment. More generally, any low-cost mock-up object can be processed to have the appearance of expensive, high-quality materials. We demonstrate a new system that allows fast, intuitive material replacement in photographs. We extend recent work in ...

Recent developments in technology mean that it is becoming increasingly possible to support collaboration around digital photos. This makes an exploration of the existing collocated social practices that are associated with photos both timely and relevant. This workshop will explore social practices in the areas of photowork, photo sharing and photo displays, with the aim of drawing together cu...

Some trauma-memory-oriented psychotherapists advise clients to review old family photo albums to cue suspected "repressed" memories of childhood sexual abuse. Old photos might cue long-forgotten memories, but when combined with other suggestive influences they might also contribute to false memories. We asked 45 undergraduates to work at remembering three school-related childhood events (two tr...

Photographs, especially of humans, are widely used as stimuli in behavioural research with pigeons. Despite their abundant use, it is not clear to what extent pigeons perceive photographs as representing three-dimensional objects. To address this question, we trained 16 pigeons to identify individual, real-life humans. This discrimination depended primarily on visual cues from the heads of the ...

Computer-generated (CG) images have achieved high levels of realism. This realism, however, comes at the cost of long and expensive manual modeling, and often humans can still distinguish between CG and real images. We introduce a new data-driven approach for rendering realistic imagery that uses a large collection of photographs gathered from online repositories. Given a CG image, we retrieve ...
