15 sept. 2008 Image of NOISE after calculation of FFT. Figure 9: ... The following picture shows what exactly an image processing does: Figure 1.
imagesc - Scale data and display as image (MATLAB Toolbox). ifftn - Compute N-D inverse fast Fourier transform (MATLAB Toolbox).
show that robustness in FFT-based scale-invariant image registra- tion depends on the image images a Matlab implementation of our algorithm requires.
Once the sinusoid image is computed and stored in im1 we compute its fast Fourier transform (FFT) with the Matlab function fft2.
