In the documentation, they said "When ksize == 1 , the Laplacian is computed by filtering the image with the following 3 \times 3 aperture: image description"

What will be the filter when the kernel size is 3,5,7? Any idea about it?

This or this for the 3x3 and 5x5 cases. The 7x7 case will be like this. Please the internet is full of examples ... you should use google decently first in the future before asking a question ...
