As explained in Eq. (4.9-1), it is possible to obtain the transfer function, HHP, of a highpass filter from the transfer function of a lowpass filter as

Using the information given in Problem 4.31, what is the form of the spatial domain Gaussian highpass filter?

4.31 A continuous Gaussian lowpass filter in the continuous frequency domain has the transfer function

Show that the corresponding filter in the spatial domain is
