... 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 ...

... K-L coordinate system, where all switching A reference vector consists of three sine waves of equal vectors are in integer form. Therefore, the number of amplitude and frequency, which are phase-shifted by 120o. It bits required for the switching vector representation is generated by utilizing the sinewave generator from the in fixed-point format is much ...
