simultaneous estimation of the range and the angle of close emitters usually requires a multidimensional search. this paper proposes analgorithm to improve the position of an element for arrays designed on the basis of some certain or random rules. in the proposed method,one element moves along the same previous direction, maintaining its vertical distance from each source, to reach a constella...

My project aims at detecting text segments in an image of a natural scene, by using an enhanced version of the Stroke Width Transform [1]. The application receives an RGB image to search in, and returns a new image where the discovered text segments are marked. Due to the features of the SWT, the resulting system is able to detect text regardless of its scale, direction, font and language.

Within the recently proposed Universal Booleanization framework, we consider the CUMULATIVE constraint, for which the original Boolean encoding proves ineffective, and present a new Boolean encoding that causes the SAT solver to simulate, largely, the search strategy used by some of the best-performing native methods. Apart from providing motivation for future research in a similar direction, w...

in this paper, we present a full newton step feasible interior-pointmethod for circular cone optimization by using euclidean jordanalgebra. the search direction is based on the nesterov-todd scalingscheme, and only full-newton step is used at each iteration.furthermore, we derive the iteration bound that coincides with thecurrently best known iteration bound for small-update methods.

due to the fact that the error surface of adaptive infinite impulse response (iir) systems is generally nonlinear and multimodal, the conventional derivative based techniques fail when used in adaptive identification of such systems. in this case, global optimization techniques are required in order to avoid the local minima. harmony search (hs), a musical inspired metaheuristic, is a recently ...
