New eyes for robotics

This paper describes an imaging system that has been designed to facilitate robotic tasks of motion. The system consists of a number of cameras in a network arranged so that they sample different parts of the visual sphere. This geometric configuration has provable advantages compared to small field of view cameras for the estimation of the system’s own motion and consequently the estimation of...

New Eyes for Old

"To look into happiness through another man's eycs."-Shakespeare. IN the last decade corneal grafting has come very much into its own and is now a recognised ophthalmic surgical procedure, practised in every ophthalmic centre throughout the world. Requirements for grafting are very precise and in each region one centre specialises more and more in this operation, and round that centre has been ...

Eyes from Eyes: New Cameras for Structure from Motion

We investigate the relationship between camera design and the problem of recovering the motion and structure of a scene from video data. The visual information that could possibly be obtained is described by the plenoptic function. A camera can be viewed as a device that captures a subset of this function, that is, it measures some of the light rays in some part of the space. The information co...

Pentacam opens eyes to new diagnostic possibilities

[Chicken eyes: new state of matter].

Matter has three states or forms of aggregation: solid, liquid and gaseous. When referring to matter and its states, we imagine quantum physicists, chemists and engineers in big laboratories or in particle accelerators to which basic researchers have little or no access. The least we could imagine is physicists describing a new state of matter in the eyes of a common chicken and, what is even m...
