Many important classification problems are emphpolychotomies, emphi.e. the data are organized into K classes with K>2. Given an unknown function F:Omegato1,dots,K representing a polychotomy, an algorithm aimed at ``learning'' this polychotomy ...
In this paper, we show that, given video sequences of a moving person acquired with a multi-camera system, we can track joint locations during the movement and recover shape information. We outline techniques for fitting a simplified model to the noisy 3-D ...
We show that the complete information that is available after an image has been encoded is not just an approximate quantized image version, but a whole set of consistent images that contains the original image by necessity. From this starting point, we dev ...
This paper investigates the problems that arise when application requirements command that autonomous spatial databases be integrated into a federated one. The paper focuses on the most critical issues raised by the integration of databases of different sc ...
Many important classification problems are \emph{polychotomies}, \emph{i.e.} the data are organized into K classes with K>2. Given an unknown function F:Ømega→{1,…,K} representing a polychotomy, an algorithm aimed at ``learning'' this p ...
We explain how to forge public parameters for the Digital Signature Standard with two known messages which always produce the same set of valid signatures (what we call a collision). This attack is thwarted by using the generation algorithm suggested in th ...
We have studied the luminescence of narrow quantum wires at photoexcitation densities of up to similar to 3 x 10(6) cm(-1). We show that even at these densities, which are well above the expected Mott density of 8 x 10(5) cm(-1), excitonic recombination do ...
Evolutionary robotics - as other adaptive methods, such as reinforcement learning and learning classifier systems - can take considerable time and resources which require a careful evaluation of the hardware tools and methodologies employed. We outline a s ...
Weak field piezoelectric coefficient and strain were investigated in ferroelectric SrBi2Ta2O9 (SET) thin films by means of optical interferometry. Though the maximum polarization and dielectric constant were small enough (7 mu C/cm(2) and 150, respectively ...
