Hermitian wavelets are a family of continuous wavelets, used in the continuous wavelet transform. The nth Hermitian wavelet is defined as the nth derivative of a Gaussian:
where
denotes the nth Hermite polynomial.
The normalisation coefficient cn is given by:
The prefactor CΨ in the resolution of the identity of the continuous wavelet transform for this wavelet is given by:
i.e. Hermitian wavelets are admissible
