WebTo compute the actual kernel elements you may scale the gaussian bell to the kernel grid (choose an arbitrary e.g. sigma = 1 and an arbitrary range e.g. -2*sigma ... 2*sigma) and normalize it, s.t. the elements sum to one. To achieve this, if you want to support arbitrary kernel sizes, you might want to adapt the sigma to the required kernel size.
