filter_DOOG_1D

PURPOSE ^

1D difference of offset Gaussian (DooG) filters.

SYNOPSIS ^

function dG = filter_DOOG_1D( r, sig, deriv, show )

DESCRIPTION ^

 1D difference of offset Gaussian (DooG) filters.

 Creates a 2D derivative of Gaussian kernel.  Use primarily for visualization purposes.
 For filtering better to use the indvidiual seperable kernels for efficiency purposes.
 
 INPUTS
   r       - final mask will have length 2r+1
   sig     - sigma for Gaussian 
   deriv   - order of derivative 
   show    - [optional] figure to use for display (no display if == 0)

 OUTPUTS
   dG      - The derivative of Gaussian mask

 EXAMPLE
   dG = filter_DOOG_1D( 11, 2, 3, 1 );
