If, Fhp(u, v)=F(u, v) – Flp(u, v) and Flp(u, v) = Hlp(u, v)F(u, v), where F(u, v) is the image in frequency domain with Fhp(u, v) its highpass filtered version, Flp(u, v) its lowpass filtered component and Hlp(u, v) the transfer function of a lowpass filter. Then, unsharp masking can be implemented directly in frequency domain by using a filter. Which of the following is the required filter?$ |
A. | H<sub>hp</sub>(u, v) = H<sub>lp</sub>(u, v) |
B. | H<sub>hp</sub>(u, v) = 1 + H<sub>lp</sub>(u, v) |
C. | H<sub>hp</sub>(u, v) = – H<sub>lp</sub>(u, v) |
D. | H<sub>hp</sub>(u, v) = 1 – H<sub>lp</sub>(u, v) |
