WebJun 13, 2024 · I'm trying to implement diffusion of a circle through convolution with the 2d gaussian kernel. The convolution is between the Gaussian kernel an the function u, which helps describe the circle by being +1 inside the circle and -1 outside.The Gaussian kernel is . In physics and mathematics, the Fourier transform (FT) is a transform that converts a function into a form that describes the frequencies present in the original function. The output of the transform is a complex-valued function of frequency. The term Fourier transform refers to both this complex-valued function and the mathematical operation. When a distinction needs to be made the Fourier transform is sometimes called the frequency domain representation of the original function. The …
