Robust and optimal use of information in stereo vision

Article Abstract:

The traditional Bayesian approach to perception presupposes that human performance in the use of the source of ey-position information can be usefully analyzed by comparison with an observer. It is argued that the comparison observer needs to be statistically robust as well, resulting in qualitatively new behaviours. The Bayesian analysis can provide a reliable and plausible algorithm that recovers eye position ahead of the solution of the classic stereo-correspondence problem.

Solitons light the way

Article Abstract:

Spatial solitons, or self-trapped beams, have been discovered that are incoherent, yet maintain a well-defined, constant and smooth outline in photorefractive materials. This first observation of self-trapping for wave-packets that are spatially and temporally incoherent opens up the possibility of all-optical processors or optical soliton communication systems.
