WebOur hybrid regularizations rely on Tikhonov and total variation (TV) functionals, from which we build two classes of hybrid regularizers: the first class is simply obtained by a convex combination (CC) of the two functionals, while the second relies … WebI The definition of convolution of two functions also holds in the case that one of the functions is a generalized function, like Dirac’s delta. Convolution of two functions. Example Find the convolution of f (t) = e−t and g(t) = sin(t). Solution: By definition: (f ∗ g)(t) = Z t 0 e−τ sin(t − τ) dτ. Integrate by parts twice: Z t 0
