What you can do is create a grid of 2D spatial co-ordinates using meshgrid that is the same size as the Gaussian filter mask you are creating. I'm going to assume that N is odd to make my life easier. This will allow for the spatial co-ordinates to be symmetric all around the mask. highland in hotelsWebVery often, the sum of coefficients of a high-pass filter is zero (a constant signal is zeroe out), thus it cannot be used for normalization. Yet, many other choices are possible. So if you want to preserve the average value of the data, in time you normalize so that the coefficients sum to one. how is golden gate university
