Which of the following a transfer function of High frequency emphasis

1.	Which of the following a transfer function of High frequency emphasis {Hhfe(u, v)} for Hhp(u, v) being the highpass filtered version of image?(a) Hhfe(u, v) = 1 – Hhp(u, v)(b) Hhfe(u, v) = a – Hhp(u, v), a≥0(c) Hhfe(u, v) = 1 – b Hhp(u, v), a≥0 and b>a(d) Hhfe(u, v) = a + b Hhp(u, v), a≥0 and b>aI have been asked this question during an interview.This question is from Unsharp Masking, High-boost filtering and Emphasis Filtering topic in section Intensity Transformations and Spatial Filtering of Digital Image Processing
Answer» Right answer is (d) Hhfe(u, v) = a + B Hhp(u, v), a≥0 and b>a The best I can explain: The TRANSFER function of High FREQUENCY emphasis is given as:Hhfe(u, v) = a + b Hhp(u, v), a≥0 and b>a.
