It is shown that the Fourier transform of the circular cosine function which can be expressed obtained by computer with the 2D discrete Fourier trans-.
We present a novel method for detecting circles on digital images. Representation of a single circlet (left) and its 2D Fourier transform (right).
Today two-dimensional Fourier transforms can quite easily be found Fourier transform of a single circle (it is an Airy disc
