Wavelet Transformation
Wavelet transformation is one of the most practical mathematical transformations in the field of image processing, especially image and signal processing. Depending on the nature of the multiresolution analysis, Wavelet transformation become more accessible and powerful tools. In this paper, we refer to the mathematical foundations of this transformation. Introduction: The...
متن کاملAnalysis of Harmonics of Electric Traction System using Wavelet Transform
Wavelet Transform is a mathematical tool for time frequency analysis of non stationary signals like the current waveform in electric traction system. The locomotives used in traction system have different types of traction motors –dc and three phase ac motors with different methods of speed control. Hence technologies will be different depending on the type of locomotives. The nature of the loa...
متن کاملAnalysis and Estimation of Harmonics Using Wavelet Technique
The paper develops an approach based on wavelet technique for the evaluation and estimation of harmonic contents of power system waveform. The proposed algorithm decomposes the signal waveforms into the uniform frequency sub-bands corresponding to the odd harmonic components of the signal. The proposed implementation of algorithm determines the frequency bands of harmonics which retain both the...
متن کاملIris Recognition using Wavelet Transformation
The demand for an accurate biometric system that provides reliable identification and verification of an individual has increased over the years. A biometric system that provides reliable and accurate identification of an individual is an iris recognition system. In which paper describes the segmentation and the normalization processing for biometric iris recognition system, implemented and val...
متن کاملGraph Transformation for Communication Minimization Using Retiming
Nested loops are normally the most time intensive tasks in computer algorithms. These loops often include multiple dependencies between arrays that impose communication constraints when used in multiprocessor systems. These dependencies may be between dependent arrays (loop dependencies), or between independent arrays (data dependencies). In this paper, reducing the communication caused by data...
