In this paper we introduce a novel real-time rendering technique for camera deformations that can be applied to lens distortions and non-realistic projections. Our technique is based on vertex shader textures and presents a hybrid approach working in both, image and object space.

In this paper we introduce Camera Adversaria; a mobile app designed to disrupt the automatic surveillance of personal photographs by technology companies. The app leverages the brittleness of deep neural networks with respect to high-frequency signals, adding generative adversarial perturbations to users' photographs. These perturbations confound image

Shoot Cut & Play Camera (SCP.Camera) is an application combining a real-time montage interface and an immersive device. It provides to film-maker or camera operator an easy tool to set up their work or previsualization. User can activate actors animations, record the virtual world, and edit sequences before exporting them to a 3D software.

AbstractThe “first look” phase of planetary imaging has been completed, with many spectacular discoveries made by a wide variety of cameras and spacecraft. Now that planetary scientists have a better idea about what is out there, new cameras can be developed to address specific questions in greater depth. Ideally, these cameras would be fully optimized

Wearing body cameras at work is a terrible idea, especially in settings where establishing a trusting therapeutic relationship is vital (readers' panel, 14 June).

We introduce the occlusion camera: a non-pinhole camera with 3D distorted rays. Some of the rays sample surfaces that are occluded in the reference view, while the rest sample visible surfaces. The extra samples alleviate disocclusion errors. The silhouette curves are pushed back, so nearly visible samples become visible.

Cardiac imaging with radiotracers plays an important role in patient evaluation, and the development of suitable imaging instruments has been crucial. While initially performed with the rectilinear scanner that slowly transmitted, in a row-by-row fashion, cardiac count distributions onto various printing media, the Anger scintillation camera allowed ...

We develop protocols for an authenticated camera that allows people to verify that a given digital image was taken by a specific camera at a specific time and specific place. These protocols require interaction between the camera and base station both before and after a series of images are taken.

I built a camera for exploring and experimenting with the urban environment. The camera doesn't sense light, but rather things that the eye can't see like CO2, temperature, wind, etc. I plan to try out this "camera for the invisible" with urban-explorers-to-be, guided by Duckworth's Piagetian-derived Critical Exploration methodology.

This photo-essay is about aspects of contemporary urban childhood. Its origins lie in a piece of fieldwork carried out in a children's playground in Manchester. I was interested in understanding how children explored and used space; and I wanted to find ways of working with children that gave them some agency in the research process.
