Edge Detection Using Fourier Coefficients
1. INTRODUCTION. Edge detection and the detection of discontinuities are important in many fields. In image processing, for example, one often needs to determine the boundaries of the items of which a picture is composed. (For more information about edge detection in image processing, see [10].) We consider the problem of detecting the edges present in a function when given the Fourier coeffici...
متن کاملAuto-Tuning Using Fourier Coefficients
The Fourier transform is an integral part of signal processing of any kind. To be able to analyze an input signal as a superposition of infinitely many signals of different frequency allows for manipulation of the coefficients and, after completing the inverse Fourier transform, interesting effects on the initial signal. Thus, in my project I focused on creating pitch correction effects as seen...
متن کاملMicrophone Classification Using Fourier Coefficients
Media forensics tries to determine the originating device of a signal. We apply this paradigm to microphone forensics, determining the microphone model used to record a given audio sample. Our approach is to extract a Fourier coefficient histogram of near-silence segments of the recording as the feature vector and to use machine learning techniques for the classification. Our test goals are to ...
متن کاملEdge Detection from Two-Dimensional Fourier Data using Gaussian Mollifiers
This paper discusses the detection of edges from two-dimensional truncated Fourier spectral data. Compared to edge detection from pixel data, this is a more challenging problem since we seek accurate local information from a small number of often noisy global measurements. We propose a highly effective algorithm using a specific class of spectral mollifiers which converges uniformly to sharp pe...
متن کاملQuad-pixel edge detection using neural network
One of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. Several edge detectors have been developed in the past decades, although no single edge detector...
