چکیده

In this paper, we introduce a multiscale operator which, together with some morphological tools, can be used to reconnect broken components of an image. This operator extracts the orientation field from the image components and can be applied to both binary and grayscale pictures. Although we illustrate its application in the fingerprint domain, the approach described here can be easily extended to images whose components exhibit well-defined directional information. Key-words: Fingerprints, Multiscale Directional Information, Mathematical Morphology, Watersheds.

INSTITUTO DE COMPUTAÇÃO UNIVERSIDADE ESTADUAL DE CAMPINAS Robust Scheduler for Grid Networks

Imprecise input data imposes additional challenges to grid scheduling. This paper introduces a novel scheduler based on fuzzy optimization called IP-FULL-FUZZY which considers uncertainties of both application demands and of resource availability. The effectiveness of the proposed scheduler is compared to those of a non-fuzzy scheduler as well as to those of a fuzzy scheduler which considers on...
