Laplace filter of an image (2D wave)

Hi All,
I am an Igor user since some years, but never programmed too much (just very basic codes).
I need to do some analyses of an image (2D wave) but did not find any solution yet. Hopefully someone can help me.
I should do a Laplacian of Gaussian filtering, and found out that there is the possibility to use the Edge Detection tool with the Marr method. However, the Marr function also detects zero crossings afterwards, which I would like to avoid.
Is there any way to split this Marr algorithm to have only the Laplacian of Gaussian filtering?
Otherwise, can someone help me to do a Laplacian of Gaussian filtering in an alternative way?
Thanks a lot,
Marco
