Computer Sciences and Information Solutions Essay Case study COMPUTER SAVOIR AND INFORMATION TECHNOLOGIES Exercise A From the above, image is original image, 2 is Fourier transform of image though 3 is a centered Fourier transmute regarding image. It seems like, the original photograph has a decreased frequency from the corners although frequency in the middle is remarkably high. In addition , it has a razor-sharp edge in the middle indicating precisely how sharp right lines can be employed in manufacturing of significant images. Significant, the fourier transform connected with image 3 has a higher frequency at the blades and lighter in weight angles connoting low frequency. Furthermore, picture 1 along with 3 are generally opposite of every other. The actual centred fourier image three or more is an inversion of graphic; has higher frequency in the 4 corners and light fluffy edges inside the central series. Read more
