dc.description.abstract | In this paper, we will study image processing in the frequency domain and its related Fourier transforms. Filtering in the frequency domain is essentially the same with filtering in the spatial domain, so we have a choice of using the domain that will be easier and faster in calculating or making filtering algorithms. Furthermore, we will see the properties of energy distribution of an image. Synthetically, a nice filter, known as the Wiener filter, is shown and will be implemented for analysis. | - |
