hi guys,, i have question about filter laplacien,,
[0 -1 0 * [28 31 30 = [ 0 2 3
-1 4 -1 30 32 27 = 4 13 0
0 -1 0 ] 29 27 30 ] 7 0 1 ]..

I have no idea. It's not a Laplacian as if you convolve a kernel with an image. It's not a convolution, correlation, or normalized cross correlation. I don't know what it is. Where did you get it, and why do you think it might be correct?
