Fast distance transform computation using dual scan line propagation

We present two fast algorithms that approximate the distance transformation of 2D binary images. Distance transformation finds the minimum distances of all data points from a set of given object points, however, such an exhaustive search for the minimum distances is infeasible in larger data spaces. Unlike the conventional approaches, we extract the minimum distances with no explicit distance c...

Lossy Transmission Line Response via Numerical Laplace Transform Inversion

An efficient transient analysis of lossy lines with nonlinear loads requires the ability to compute and represent a suitable set of line impulse responses. In this paper, we propose the evaluation of the matched-line impulse responses by means of an algorithm for the numerical inversion of the Laplace Transform. Based on a discussion of the structure of the impulse responses, we demonstrate how...

Fast Inversion of the Exponential Radon Transform by Using Fast Laplace Transforms

Abstract. The Fourier slice theorem used for the standard Radon transform generalizes to a Laplace counterpart when considering the exponential Radon transform. We show how to use this fact in combination with using algorithms for unequally spaced fast Laplace transforms to construct fast and accurate methods for computing, both the forward exponential Radon transform and the corresponding back...

Accurate Fault Classification of Transmission Line Using Wavelet Transform and Probabilistic Neural Network

Fault classification in distance protection of transmission lines, with considering the wide variation in the fault operating conditions, has been very challenging task. This paper presents a probabilistic neural network (PNN) and new feature selection technique for fault classification in transmission lines. Initially, wavelet transform is used for feature extraction from half cycle of post-fa...
