Notation: $\mathcal F\left\{a\right\}$ denotes applying the discrete forward Fourier transform to the histogram $a$. Similarly for $\mathcal F^{-1}\left\{a\right\}$ and the discrete inverse … Fourier transform. Capitals represent the discrete fast Fourier transform of the lower-case counterpart, e.g. $A = \mathcal F\left\{a\right\}$. The convolution of two histograms $f$ and $g$ is denoted $f …
