Shape recognition using orientational and morphological scale‐spaces of curvatures

IET Computer Vision, 2015
In this study, a scale‐invariant representation for closed planar curves (silhouettes) is proposed. The orientations of all points within the Gaussian scale‐space of the curve are extracted.

Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]

, 2007
The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence
