Some Applications of Fourier Transformation

Abstract

In this research some applications to Fourier transform in one dimension and in two dimensions for separated data, first in one dimension, where the signal from the study during their characteristics as well as how to remove noise from the signal. Second, in two dimensions, it was a method to detect basic shapes in the image by selecting the desired first and then match the spectrum of each shape in the image to detect the fold. In the final stage of the research were studied diffraction pattern from a circular slit and improve the visibility of this pattern of diffraction . All methods were conducted by Fourier transform has appeared good results have been clarified through research.
