Answer» RIGHT option is (c) Emphasized filtering Explanation: The TRANSFER FUNCTION of HIGH frequency emphasis is given as: Hhfe(u, v) = a + b Hhp(u, v), for Hhp(u, v) being the highpass filtered version of image,a≥0 and b>a. When b increases past 1, the high frequency are emphasized and so the filtering PROCESS is better known as Emphasized filtering.
