awhere F* is the complex conjugate of F, the shift theorem guarantees that the phase of the cross-power spectrum is equivalent to the phase difference between the images. By taking inverse Fourier transform of the representation in the frequency domain, we will have a function that is an imp...
aWe choose wavelet based on the characteristics as follows : a) A set of length and : That is speed when time or frequency tends to infinity, and from a limited value convergence to zero. b) Symmetry: Wavelet with symmetry means during the Mallat decomposition filter has linear phase, this...
