State determination: An iterative algorithm

An Iterative Fingerprint Enhancement Algorithm Based on Accurate Determination of Orientation Flow

We describe an algorithm to enhance and binarize a fingerprint image. The algorithm is based on accurate determination of orientation flow of the ridges of the fingerprint image by computing variance of the neighborhood pixels around a pixel in different directions. We show that an iterative algorithm which captures the mutual interdependence of orientation flow computation, enhancement and bin...

An iterative algorithm for the determination of voronoi vertices in polygonal and non-polygonal domains

We propose a new iterative algorithm for the computation of the vertices of a Voronoi diagram for a set of geometric objects of the euclidean plane. Each one of these vertices is the centre of the circle “touching” a triple of objects (passing through points or tangent to any other geometric object). The algorithm starts with an initial triple of points pertaining to each one of the three objec...

An iterative mixed1 norm image restoration algorithm

In this paper; we propose an iterative mired norm image restoration algorithm. A functional which combines the least mean squares (LMS) and the least mean fourth (LMF) functionals is proposed. A function of the kurtosis: is used to determine the relative importance between the L A 8 and the LMF functionals. An iterative algorithm is utilized for obtaining a solution and its convergence is analy...

An Iterative Algorithm for Graph De-anonymization

The availability of social network data is indispensable for numerous types of research. Nevertheless, data owners are often reluctant to release social network data, as the release may reveal the private information of the individuals involved in the data. To address this problem, several techniques have been proposed to anonymize social networks for privacy preserving publications. To evaluat...
