laplacian filter

Hi,

 

I have a simple question. I have a sample data (64x64 pixels) of straight beam projection using gaussian function. The problem is how can I implement laplacian filter with the following kernel (3 x 3) : [ 0  -1  0 , -1  4  -1 , 0  -1   0]  to the given data? Any examples which I can referred?

 

Thank you.

Applying a LaPlace filter is simply doing a convolution with the 3x3 kernel that you showed.  Try LabVIEW "Help", "Convolution".  Then try to write your own program, test it, and if you have further questions, post a followup question along with your VI.
