... kernel given in Eq. 6. The Gaussian high pass (GHP) filter: it is a type of high pass filter that passes frequencies higher than cut-off frequency and suppresses lower ones in the frequency domain. Hence, a high pass filter improves the visibility of details and denotes the edges of the images. The ...
