Answer» The correct ANSWER is (d) All of the mentioned The explanation is: A high-boost FILTER is a generalized FORM of unsharp mask and is GIVEN by: fhb = A f(x, y) – f (x, y) Or, fhb = (A – 1) f(x, y) + f(x, y) – f(x, y), that can be written as fhb = (A – 1) f(x, y) + FS(x, y), where fs(x, y) = f(x, y) – f (x, y).
