| Description: | This plugin calculates a 2D Gaussian filter. 
 The plugin have the following input paramters:
 
 
	Gaussian filters are important in many signal processing, image processing,
     and communication applications. These filters are characterized by narrow bandwidths and
     sharp cutoffs. A key feature of Gaussian filters is that the Fourier transform of a Gaussian is
     also a Gaussian, so the filter has the same response shape in both the time and frequency domains.The  cutoff  parameter defines the filter cutoff-frequency.  The  DC-level  parameter defines the height of the dc-center component. |
