Hilbert transform
integral transform and linear operator that takes a function of a real variable and produces another function of a real variable with a 90 degree phase shift
Radon transform
integral transform which takes a function f defined on the plane to a function Rf defined on the (two-dimensional) space of lines in the plane, whose value at a particular line is equal to the line integral of the function over that line
