A fast mellin and scale transform
WebFast Hankel Transform References Fourier analysis is a method for expressing a function as a sum of periodic components, and for recovering the signal from those components. When both the function and its Fourier transform are replaced with discretized counterparts, it is called the discrete Fourier transform (DFT). WebA fast algorithm for the discrete-scale (and -Mellin) transform is proposed. It performs a discrete-time discrete-scale approximation of the continuous-time transform, with …

By remapping these images into log-polar space, we can recover rotation as before, and now also scaling, by phase correlation.
WebThe log-polar images are translated by 11 and -53 pixels in x and y respectively. In order to calculate the rotation and scaling we use the following formulae: s i z e = m a x ( r o w s, c o l s) = m a x ( 286, 320) log b a s e r o w s 2 = s i z e b a s e = exp log r o w s 2 s i z e = exp log 286 2 320 = 1.015 WebWe realized a Fast Mellin Transform (FMT) by exploiting the analogy between the Mellin and Fourier transforms, as a sequence of exponential time-warping, multiplication by an …
