Note that the integral values of k are taken starting from 0 and counting till N-1. k is simply a variable used to refer to the sampled value of the function. However, since IDFT is the inverse of DFT, so k is not used. Instead, ‘n’ is used. Many find it confusing which is which. gap store in tucsonWebDFT: $$ X[k] = \sum\limits_{n=0}^{N-1} x[n] e^{-j 2 \pi nk/N} $$ iDFT: $$ x[n] = \frac{1}{N} \sum\limits_{k=0}^{N-1} X[k] e^{j 2 \pi nk/N} $$ that is most fundamentally what the DFT is. it is inherently a periodic or circular thing. but the periodicity deniers like to say this about the DFT. it is true, it just doesn't change any of the above. gap store playlists

"WebThe DFT belongs to a class of transforms called orthogonal transforms, and it is not the only member of this calss used in DSP applications. Some of the more popular are the Walsh, slant, and COSINE transforms. Another class of transform, called the number theoretic transform, can be applied to fast DFTs or convolutions. " - Dft classe 2

The Fourier Transform will decompose an image into its sinus and cosines components. In other words, it will transform an image from its spatial domain to its frequency domain. The idea is that any function may be approximated exactly with the sum of infinite sinus and cosines functions. The Fourier Transform is a way how to do this.
