## Morphology in Frequency Domain

To put it simply,

[latex]GrayScale(Image) \rightarrow DFT(Image) \rightarrow f(Image) \rightarrow IDFT(Image)[/latex]

Replace $latex f(Image) = f(x)$ by any of the functions from the following table, it also shows the effect of the function on the “Lenna” image. The images show effect of morphology or filter applied in the frequency domain.
