     \textit{high frequencies provide details in pictures}
   \item A 2D \textbf{Fourier transform} translates from spatial \((x,y)\) to frequency \((u,v)\) domain
 \[
-F(u,v) = \int_{-\infty}^{+\infty} \int_{-\infty}^{+\infty} f(x,y)e^{-j2\pi(ux+uy)}dxdy
+F(u,v) = \int_{-\infty}^{+\infty} \int_{-\infty}^{+\infty} f(x,y)e^{-j2\pi(ux+vy)}dxdy
 \]
   \item The transform decomposes the domain in \textbf{periodic patterns}
   \item Adapted for discrete signals as \textbf{Discrete Fourier Transform}
