An Efficient Algorithm for the Detection of Eden [PDF]

open access: yesComplex Systems, 2013
In this paper, a polynomial time algorithm is presented for solving the Eden problem for graph cellular automata. The algorithm is based on our neighborhood elimination operation which removes local neighborhood configurations which cannot be used in a pre-image of a given configuration.

Design Criteria for InGaAs/InP Single-Photon Avalanche Diode

open access: yesIEEE Photonics Journal, 2013
We provide a detailed insight on the design of InGaAs/InP single-photon avalanche diode (SPAD) for 1.55- μm photon detection. In order to lower SPAD noise [the dark count rate (DCR)] without lowering photon detection efficiency (PDE) or increasing

Efficient detection in hyperspectral imagery [PDF]

open access: yesIEEE Transactions on Image Processing, 2001
Hyperspectral sensors collect hundreds of narrow and contiguously spaced spectral bands of data. Such sensors provide fully registered high resolution spatial and spectral images that are invaluable in discriminating between man-made objects and natural clutter backgrounds.
