Current Protocols in Cytometry, 1998
AbstractAnother critical component of an image cytometer is the camera, which converts the optical image to an electrical form to view on a monitor, record, or digitize for subsequent analysis. Any image degradation introduced at this stage affects the quality and accuracy of the system output.

Turn a Silicon Camera Into an InGaAs Camera
2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2019Short-wave infrared (SWIR) imaging has a wide range of applications for both industry and civilian. However, the InGaAs sensors commonly used for SWIR imaging suffer from a variety of drawbacks, including high price, low resolution, unstable quality, and so on.

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.

Proceedings 12th Annual Computer Security Applications Conference, 2002
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.

Proceedings of the 7th international conference on Interaction design and children, 2008
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.

Proceedings of the 4th international conference on Computer graphics and interactive techniques in Australasia and Southeast Asia, 2006
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.

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.

Successful self-regulated learning in a personalized learning environment (PLE) requires self-monitoring of the learner and reflection of learning behaviour. We introduce a tool called CAMera for monitoring and reporting on learning behaviour and thus for supporting learning reflection. The tool collects usage metadata from diverse application programs,
