Witryna1 To be more specific I want to show that impulse function in 2D can be represented as $β (r)=δ (r)/πr$. Also I want to show that each projection of a two dimensional impulse function at the origin is a Delta function. I could not find any useful information about these two problems, if anyone could help I will be appreciated. image-processing Witryna24 lip 2014 · The impulse response of a Gaussian Filter is written as a Gaussian Function as follows The Fourier Transform of a Gaussian pulse preserves its shape.
